Abstract:

The options for primary thermometry at ultra-low temperatures are rather limited. In practice, most laboratories are using 195 Pt NMR thermometers in the microkelvin range. In recent years, current sensing direct current superconducting quantum interference devices (DC-SQUIDs) have enabled the use of noise thermometry in this temperature range. Such devices have also demonstrated the potential for primary thermometry. One major advantage of noise thermometry is the fact that no driving current is needed to operate the device and thus the heat dissipation within the thermometer can be reduced to a minimum. Ultimately, the intrinsic power dissipation is given by the negligible back action of the readout SQUID. For thermometry in low-temperature experiments, current noise thermometers and magnetic flux fluctuation thermometers have proved to be most suitable. To make use of such thermometers at ultra-low temperatures, we have developed a cross-correlation technique that reduces the amplifier noise contribution to a negligible value. For this, the magnetic flux fluctuations caused by the Brownian motion of the electrons in our noise source are measured inductively by two DC-SQUID magnetometers simultaneously and the signals from these two channels are cross-correlated. Experimentally, we have characterized a thermometer made of a cold-worked high-purity copper cylinder with a diameter of 5 mm and a length of 20 mm for temperatures between 42 μ K and 0.8 K. For a given temperature, a measuring time below 1 min is sufficient to reach a precision of better than 1%. The extremely low power dissipation in the thermometer allows continuous operation without heating effects.

A major advantage of noise thermometry is the fact that no driving current is needed to operate the device and thus the heat dissipation within the thermometer can be reduced to a minimum. Such devices can be used either in primary or relative primary mode and cover typically several orders of magnitude in temperature extending into the low microkelvin regime. Here we will review recent advances of noise thermometry for ultralow temperatures.

Abstract:

Existing temperature sensors such as thermocouples and platinum resistance thermometers suffer from calibration drift, especially in harsh environments, due to mechanical and chemical changes (and transmutation in the case of nuclear applications). A solution to the drift problem is to use temperature sensors based on fundamental thermometry (primary thermometers) where the measured property is related to absolute temperature by a fundamental physical law. A Johnson noise thermometer is such a sensor and uses the measurement of the extremely small thermal voltage noise signals generated by any resistive element to determine temperature using the Johnson-Nyquist equation. A Johnson noise thermometer never needs calibration and is insensitive to the condition of the sensor material, which makes it ideally suited to long-term temperature measurement in harsh environments. These can include reactor coolant circuits, in-pile measurements, nuclear waste management and storage, and severe accident monitoring. There have been a number of previous attempts to develop a Johnson noise thermometer for the nuclear industry, but none have achieved commercialization because of technical difficulties. We describe the results of a collaboration between the National Physical Laboratory and Metrosol Limited, which has led to a new technique for measuring Johnson noise that overcomes the previous problems that have prevented commercialization. The results from a proof-of-principle prototype that demonstrates performance commensurate with the needs of nuclear applications is presented, together with details of progress towards the commercialization of the technology. The development partners have effected a step change in the application of primary thermometry to industrial applications and seek partners for field trials and further exploitation.

Abstract:

The accurate determination of the temperature of an experiment at low temperatures in high magnetic fields is difficult. We present the results of measurements made using a number of new techniques developed over the last few years. In particular we discuss the results of measurements made using a unique capacitor made with Kapton and copper in a cylindrical geometry.1 This capacitance thermometer, dubbed the "Kapacitor", is different from other low temperature thermometers in that the minimum in capacitance vs. temperature can be moved to lower temperatures (to below 20 mK) by changing the construction technique. In addition, we discuss measurements on Coulomb blockade thermometers (CBT's) that offer the possibility of true primary thermomemtry at low temperatures without any magnetic field dependence. Both of these new techniques will be compared to the standard technique of resistance thermometry using RuO chip resistors. The crucial issues of accuracy and precision, usefulness for control, and noise sensitivity will be discussed for each of these technologies. In addition, recent measurements on the magnetic behavior of RuO thermometers at low temperatures and its relationship to anomalous low field peaks in the resistance that develop at temperatures below 50 mK are also presented.

Abstract:

The use of low-temperature platforms with base temperatures below 1 K is rapidly expanding, for fundamental science, sensitive instrumentation and new technologies of potentially significant commercial impact. Precise measurement of the thermodynamic temperature of these low-temperature platforms is crucial for their operation. In this paper, we describe a practical and user-friendly primary current-sensing noise thermometer (CSNT) for reliable and traceable thermometry and the dissemination of the new kelvin in this temperature regime. Design considerations of the thermometer are discussed, including the optimization of a thermometer for the temperature range to be measured, noise sources and thermalization. We show the procedure taken to make the thermometer primary and contributions to the uncertainty budget. With standard laboratory instrumentation, a relative uncertainty of 1.53% is obtainable. Initial comparison measurements between a primary CSNT and a superconducting reference device traceable to the PLTS-2000 (Provisional Low Temperature Scale of 2000) are presented between 66 and 208 mK, showing good agreement within the k =1 calculated uncertainty.

Abstract:

The number of wireless devices has grown tremendously over the last decade. Great technology improvements and novel transceiver architectures and circuits have enabled an astonishingly expanding set of radio-frequency applications. CMOS technology played a key role in enabling a large-scale diffusion of wireless devices due to its unique advantages in cost and integration. Novel digital-intensive transceivers have taken full advantage of CMOS technology scaling predicted by Moore's law. Die-shrinking has enabled ubiquitous diffusion of low-cost, small form factor and low power wireless devices. However, Radio Frequency (RF) Power Amplifiers (PA) transceiver functionality is historically implemented in a module which is separated from the CMOS core of the transceiver. The PA is traditionally dictating power and battery life of the transceiver, thus justifying its implementation in a tailored technology. By contrast, a fully integrated CMOS transceiver with no external PA would hugely benefit in terms of reduced area and system complexity. In this work, a fully integrated prototype of a Switched-Capacitor Power Amplifier (SCPA) has been implemented in a 28nm CMOS technology. The SCPA provides the functionalities of a PA and of a Radio-Frequency Digital-to-Analog Converter (RF-DAC) in a monolithic CMOS device. The switching output stage of the SCPA enables this circuital topology to reach high efficiencies and offers excellent power handling capabilities. In this work, the properties of the SCPA are analyzed in an extensive and detailed dissertation. Nowadays Wireless Communications operate in a very crowded spectrum, with strict coexistence requirements, thus demanding a strong linearity to the RF-DAC section of the SCPA. A great part of the work of designing a good SCPA is in fact designing a good RF-DAC. To enhance RF-DAC linearity, a precision of the timing of the elements up to the ps range is required. The use of a single core-supply voltage in the whole circuit including the CMOS inverter of the switching output stage enables the use of minimum size devices, improving accuracy and speed in the timing of the elements. The whole circuit operates therefore on low core-supply voltage. Throughout this work, a detailed analysis carefully describes the electromagnetic structures which maximize power and efficiency of low-voltage SCPAs. Due to layout issues subsequent to limited available voltages, however, there is a practical limitation in the maximum achievable power of low-voltage SCPAs. In this work, a Multi-Port Monolithic Power Combiner (PC) is introduced to overcome this limitation and further enhance total achieved system power. The PC sums the power of a collection of SCPAs to a single output, allowing higher output powers at a high efficiency. Benefits, drawbacks and design of SCPA PCs are discussed in this work. The implemented circuit features the combination of four differential SCPAs through a four-way monolithic PC and is simulated to obtain a maximum drain efficiency of 44% at a peak output power of 29dBm on 1.1V supply voltage. Extensive spectrum analysis offers full evaluation of system performances. After exploring state-of-the-art possibilities offered by an advanced 28nm CMOS technology, this work predicts through rigorous theoretical analysis the expected evolution of SCPA performances with the scaling of CMOS Technologies. The encouraging forecast further emphasizes the importance of SCPA circuits for the future of high-performance Wireless Communications.
Il numero dei dispositivi senza fili è cresciuto esponenzialmente negli ultimi dieci anni. Grandi progressi tecnologici e nuove architetture di ricetrasmettitori hanno reso possibile un'impressionante insieme di applicazioni a radio-frequenza. La tecnologia CMOS ha giocato un ruolo centrale nel rendere possibile una diffusione in larga scala di dispositivi senza fili grazie ai suoi esclusivi vantaggi in termini di costo e integrazione. Nuovi ricetrasmettitori marcatamente digitali hanno preso pieno vantaggio dell'evoluzione tecnologica prevista dalla legge di Moore. La riduzione della dimensione degli integrati microelettronici ha permesso una diffusione capillare di dispositivi senza fili a basso costo, di ridotte dimensioni e dal basso consumo. D'altra parte, la funzionalità degli amplificatori di potenza (PA) per radio frequenza (RF) è storicamente implementata in un modulo che è separato dal nucleo CMOS del ricetrasmettitore. Il PA determina tradizionalmente la potenza e la durata della batteria del ricetrasmettitore, e per ciò è giustificata la sua implementazione in una tecnologia dedicata. All'opposto, un ricetrasmettitore CMOS pienamente integrato senza PA esterno beneficerebbe largamente in termini di riduzione di area e di complessità di sistema. In questo lavoro, un prototipo completamente integrato di Amplificatore di Potenza a Capacità Commutate (SCPA) è stato implementato in una tecnologia CMOS a 28nm. L'SCPA fornisce le funzionalità di un PA e di un Convertitore Digitale-Analogico in Radio Frequenza (RF-DAC) in un dispositivo CMOS monolitico. Lo stadio d'uscita commutato dell'SCPA rende questa topologia capace di raggiungere alte efficienze e offre un'eccellente capacità di generare potenza. In questo lavoro, le proprietà dell'SCPA sono analizzate in una discussione estensiva e dettagliata. Le comunicazioni senza fili di oggi operano in uno spettro molto affollato, con requisiti di coesistenza molto stretti, che quindi richiedono un'alta linearità alla sezione RF-DAC dell'SCPA. Una grande parte del lavoro di progetto di un SCPA è infatti progettare un buon RF-DAC. Per migliorare la linearità dell'RF-DAC, è richiesta una precisione della temporizzazione degli elementi fino all'ordine di grandezza dei ps. L'uso di una singola tensione di alimentazione, incluso l'invertitore CMOS dello stadio di uscita commutato, rende possibile l'uso di dispositivi di dimensione minima, migliorando l'accuratezza e la velocità della temporizzazione degli elementi. L'intero circuito opera quindi su una bassa tensione di alimentazione. Nel corso di questo lavoro, un'analisi dettagliata descrive con attenzione le strutture elettromagnetiche che massimizzano la potenza e l'efficienza degli SCPA a bassa tensione. A causa di problemi di maschere dovuti alle limitate tensioni disponibili, comunque, c'è una limitazione pratica nella massima potenza che un SCPA a bassa tensione può raggiungere. In questo lavoro, un Sommatore di Potenza Monolitico Multi-Porta (PC) è introdotto per superare questa limitazione e incrementare ulteriormente la potenza di sistema totale. Il PC somma la potenza di una collezione di SCPA in una singola uscita, rendendo possibili potenze più alte con un'alta efficienza. I benefici, i problemi e il progetto dei PC per SCPA sono discussi in questo lavoro. Il circuito progettato comprende la combinazione di quattro SCPA attraverso un Sommatore di Potenza (PC) monolitico ed è simulato ottenere un'efficienza massima di collettore del 44% con una potenza di picco di 29dBm da una tensione di alimentazione di 1.1V. Estensive analisi di spettro offrono una completa valutazione delle prestazioni di sistema. Dopo aver esplorato le prestazioni dello stato-dell'arte offerte da un'avanzata tecnologia CMOS a 28nm, questo lavoro predice attraverso un'analisi teorica rigorosa l'evoluzione attesa delle prestazioni dell'SCPA con l'evoluzione delle tecnologie CMOS. L'incoraggiante previsione enfatizza ulteriormente l'importanza dei circuiti SCPA per il futuro delle comunicazioni senza fili ad alte prestazioni.

Abstract:

Ce travail de thèse présente un dispositif expérimental original permettant la mesure, dans des conditions comparables, des fluctuations de l'aimantation d'un échantillon et de sa réponse à un champ magnétique. Une comparaison quantitative permet, via le théorème de fluctuation-dissipation, une mesure absolue de la température lorsque l'échantillon est à l'équilibre thermodynamique. Pour des systèmes vitreux, la "température effective" ---une extension conservant le formalisme du théorème de fluctuation-dissipation de la température pour les système à faible production d'entropie--- est rendue accessible. Un échantillon "verre de spin" ($CdCr_{1,7}In_{0,3}S_4$) aux propriétés vitreuses étudiées depuis de nombreuses années a permis cette mesure. Le régime fortement vieillissant, non-stationnaire, est étudié; la mesure nécessaire des fluctuations thermiques est très délicates (l'amplitude de ces fluctuations correspond à la réponse de l'échantillon à des variations de l'ordre du millionième du champ magnétique terrestre).
Les résultats obtenus montrent en premier lieu une dynamique de quasi-équilibre, confirmant des résultats précédents. Le régime fortement vieillissant est maintenant également atteint. Toutefois, les mesures ne peuvent pas être traduites directement en terme de température effective, car expérimentalement, on observe systématiquement la coexistence d'une dynamique stationnaire et de la dynamique de vieillissement. Une analyse par scaling est proposée pour séparer ces deux contributions. Sous réserve de validité de cette analyse, les mesures confirment alors les principales caractéristiques attendues pour la température effective, et notamment son indépendance en fonction de l'âge du système.
Les différents modèles connus ne permettent cependant pas d'expliquer complètement toutes les caractéristiques de la température effective mesurée, certaines d'entre elles paraissant encore antinomiques...

Abstract:

In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically predicted that a certain class of fractional QH phases may also contain upstream modes together with the downstream ones (counter-propagating modes). Further, these upstream modes may not carry any electrical current but can carry energy. Detecting the charge-neutral upstream modes is challenging and remains critical for the emergence of renormalized modes with exotic quantum statistics for quantum computing. In this context, QH of graphene is an ideal platform with more degrees of freedom like spin, valley, and orbital together with a unique half-filled zeroth Landau level (ν=0 state), where the bulk is not vanilla type but rather can host canted antiferromagnetic (CAF) phase with charge-neutral Goldstone modes or isospin-ferromagnetic (FM) phase (ν≠0) with spin-wave excitations like magnon, etc. This thesis attempts to detect these charge-neutral upstream modes and spin-wave excitations in graphene QH using “Noise Thermometry”, based on heat transport. First, we present our study on detection of charge neutral upstream modes at hole-conjugate ν=2/3 and 3/5 fractional QH states of bilayer graphene. We observed excess noise along the edge in the upstream direction at ν=2/3 and 3/5 states, providing smoking gun evidence of upstream modes at these fillings, while no noise is detected at integer and particle-like FQH states. The channel length and temperature dependence of the noise in upstream direction at ν=2/3, together with remarkable agreement of theoretically calculated noise, suggest ballistic nature of upstream modes, quite distinct from the diffusive nature reported in GaAs/AlGaAs based system. Next, using similar technique to detect heat flow in the upstream direction, we detected charge neutral spin-wave excitations at the ν=2 QH ferromagnet in bilayer graphene. We generate spin excitation by creating an imbalance in the chemical potential (> Zeeman energy gap) between the edge states of opposite spin, and detect it in the upstream direction due to heat transport by spin-wave. The observed threshold of bias energy (where spin excitation occurs) at different magnetic fields agrees with the expected Zeeman gap. In a slightly different measurement scheme, we tried to detect heat transport signature of charge neutral Goldstone modes present at ν=0 CAF state. Our findings shed light on the competition between the heat transport via goldstone modes and phonon. Next, we study the effect of periodic magnetic field on Hall conctivity of graphene. The periodic magnetic field over graphene was created by Abrikosov vortices of a type-II superconductor (NbSe2 in this work). We found a density-dependent reduction of the Hall conductivity of graphene as the temperature is lowered from above the superconducting critical temperature of NbSe2, where the magnetic field is uniform, to below, where the magnetic field bunches into an Abrikosov flux lattice.

La0.75Ca0.15Sr0.1MnO3 (LCSMO) thin films were grown on NdGaO3(110) substrates by using RF magnetron sputtering. Here the samples were deposited at different growth temperatures to probe the effect of growth temperature on this film properties. We used the standard 4-probe measurement to obtain the resistance-temperature curves. The crystalline structure and the strains in films were charactered by the X-ray diffractometer. The optimum performance is found in LCSMO grown at 610 ℃ with low strain, which show a temperature coefficient of resistance (TCR) ~ 4.9 %K-1 at 301 K and a noise equivalent temperature (NET) of 8×10-7 KHz-0.5 at 300 K with f = 30 Hz and I = 0.3 mA. This obtained NET value is much lower than those of other uncooled thermometers such as semiconducting YBa2Cu3O6, or vanadium oxides. We demonstrate that the LCSMO films have real potential for the application on uncooled bolometric devices.

Abstract:

The proposed IoT based farming system was built with the Arduino board, Node MCU and various sensors. The IoT platform used to support this project was Blynk. The prototype consists of two nodes that are transmitter node and receiver node. The transmitter node sends the sensing data including temperature, humidity, motion, and soil moisture to the receiver node. Meanwhile, the water pump was activated when the soil moisture was lower than 25% and off if the soil moisture was higher or equal to 25%. In receiver node, the various data was displayed in the OLED display and sent to the Blynk cloud simultaneously. The users of this system can monitor their crops using mobile application and websites. The DHT22 was able to measure high accurate data by comparing the results with infrared thermometer sensor and the PIR motion sensor detects the far motion up to 8 meters. The maximum RSSI value of LoRa WAN data transmission in this project was up to -86.9dBm when the distance between transmitter and receiver was 10 meters but the wireless connection was still function because the result is still not lower than the noise floor which is -120dBm and there will be no loss of data in LoRaWAN, this proved LoRa was the suitable network architecture in the field of agriculture.

Abstract:

Temperature is a key process variable at any nuclear power plant (NPP). The harsh reactor environment causes all sensor properties to drift over time. At the higher temperatures of advanced NPPs the drift occurs more rapidly. Johnson noise is a fundamental expression of temperature and as such is immune to drift in a sensor’s physical condition. In and near the core, only Johnson noise thermometry (JNT) and radiation pyrometry offer the possibility for long-term, high-accuracy temperature measurement due to their fundamental natures. Small Modular Reactors (SMRs) place a higher value on long-term stability in their temperature measurements in that they produce less power per reactor core and thus cannot afford as much instrument recalibration labor as their larger brethren. The purpose of the current ORNL-led project, conducted under the Instrumentation, Controls, and Human-Machine Interface (ICHMI) research pathway of the U.S. Department of Energy (DOE) Advanced SMR Research and Development (R&D) program, is to develop and demonstrate a drift free Johnson noise-based thermometer suitable for deployment near core in advanced SMR plants.

Abstract:

The performance and accuracy of quantum electronics is substantially degraded when the temperature of the electrons in the devices is too high. The electron temperature can be reduced with appropriate thermal anchoring and by filtering both the low frequency and radio frequency noise. Ultimately, for high performance filters the electron temperature can approach the phonon temperature (as measured by resistive thermometers) in a dilution refrigerator. In this application note, the method for measuring the electron temperature in a typical quantum electronics device using Coulomb blockade thermometry is described. This technique is applied to find the readily achievable electron temperature in the device when using the QFilter provided by QDevil. With our thermometry measurements, using a single GaAs/AlGaAs quantum dot in an optimized experimental setup, we determined an electron temperature of 28 ± 2 milli-Kelvin for a dilution refrigerator base temperature of 18 milli-Kelvin.
