Повний текст джерелаThe present work mainly focuses on improving the performance of OPVCs by tailoring the donor-acceptor interface geometry and by tuning the electrical properties of interfaces with p-type molecular doping. Crystalline and uniform nanocolumns of pentacene (PEN) and diindenoperylene (DIP) were fabricated by glancing angle deposition (GLAD), forming an interdigitated donor/acceptor heterojunction with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and/or fullerene as the electron acceptor. The short circuit current of nanocolumn-based OPVCs increased significantly compared to planar heterojunction OPVCs made from the same materials. The performance improvement of OPVCs had been verified to be contributed decisively by the donor-acceptor interface area enlargement because of reduced impact of short exciton diffusion length in organic materials. P-type molecular doping as applied in polyfuran (PF) based OPVCs was investigated by using tetrafluorotetracyanoquinodimethane (F4-TCNQ) as the dopant for various doping ratios. Ultraviolet photoelectron spectroscopy (UPS) was applied to analyze the energy level shift with increasing doping ratio leading to the enlargement of the open circuit voltage in OPVCs, from 0.2 V to close to 0.4 V. Combining this observation with the results of doped polymer films, their morphology and absorption behavior, a net dipole pointing towards the donor material at the donor-acceptor interface of OPVCs is proposed. Overall, this work demonstrates the potential of both the GLAD technique and molecular electrical doping for improving the performance of OPVCs.

Повний текст джерелаThe increasing importance of portable and wearable electronics as well as embedded wireless sensor networks has made energy autonomy a critical issue. Micro-energy autonomy solutions based on the combination of energy harvesting and storage may play a decisive role. However, the short lifetime of micro-batteries is problematic. Micro-supercapacitors are a promising solution in terms of energy storage for embedded systems on the account of their important lifetime. In this work we have focused on the optimization of the performances of micro-supercapacitors in terms of energy and power density. As the capacitance is directly related to the accessible surface area of the electrodes, we have investigated the structuration of the current collectors in order to improve the performances of ruthenium oxide-based micro-supercapacitors. Two mains technics have been studied to obtain three dimensional structures. In a first phase, the oblique angle physical vapor deposition (OAD) has been investigated to fabricate a columnar gold structure, subsequently covered by an electrochemical ruthenium oxide. In a second phase, a highly porous gold architecture has been studied using electrodeposition via a hydrogen bubbles dynamic template. The ruthenium oxide electrodeposited on the resulting mesoporous gold structure shows good compatibility, in terms of homogeneous deposition, with a significant capacitance at slow rate (> 3F.cm-2) and an important cyclability. As proof of concept, a device has been designed in a stack configuration with good performances. Moreover, the technology finalized for electrodes fabrication has been transferred to the micro-scale on planar interdigitated devices using a suitable photolithography process

Повний текст джерелаA 3 axis gyroscope allows, with a single mechanical structure, the measurement of rotation rates of an object around 3 perpendicular spatial axes. Existing 3 axis microgyroscopes are scarce and typically resonating, made in silicon technology by surface micromachining, use electrostatic transductions and are designed for high volume applications where size and cost are major characteristics. In this thesis we investigated the transduction and fabrication process of a resonating 3 axis microgyroscope having piezoelectric actuation and detection, made in semi-insulating GaAs by bulk micromachining, and with performances potentially much higher than state of the art while limiting the size and cost. This microgyroscope requires a 3D piezoelectric transduction and circuitry which were modelled and optimized to reduce cross-talks effects. An original batch fabrication process was developed, modelled and characterized. This process notably makes use of very deep through wafer reactive ion etching of GaAs in a BCl3-Cl2 plasma. It is demonstrated for the first time that a through wafer highly anisotropic etching of 450 μm deep trenches can be realized owing to etching parameters optimization and the use of a resist masking layer. An original deposition and patterning process of Au/Cr electrodes on the vertical walls of an etched structure by oblique evaporation on rotated substrate through a dry film shadow mask has also been investigated in details. A fine characterization of the crystallographic structure, resistivity and mechanical stress before, during and after annealing of Au/Cr films evaporated under oblique incidence has been performed. Full microgyroscopes with the whole 3D tranduction system were realized. Preliminary characterizations of realized gyroscopes by out-of-plane and in-plane optical vibrometry demonstrated promising results. Finally, different ways to improve the design and fabrication process are proposed

Повний текст джерелаAnti-reflective (AR) coatings are widely used to improve the transmission of optical systems composed of window, lenses, separating filters,... In this thesis, the spectral ranges targeted are the extended visible [400-1800nm] and the mid infrared [3.7-4.8µm]. Thin film deposition nanostructuring method using oblique angle deposition (oblique angle deposition) PVD technique was chosen because it allows high performance AR to be considered over a wide wavelength range, by an industrial process. The introduction of porosity with the control of deposition angle is used to nanostructure the architecture of each layer and stack; a method for modifying and optimizing the optical properties of the constituent layers for optimal complete design. A mapping of the effective indices accessible by OAD has been identified for the three materials deposited (TiO2, SiO2 and Ge). However optical properties of these nanostructured layers differ greatly from those of dense layers due to the presence of anisotropy, index gradient, diffusion and absorption. Based on advanced microstructural, chemical and optical characterizations (AFM, SEM, TEM, FIB tomography, TEM tomography, EDX, EELS, spectrophotometry and generalized ellipsometry) a more complex analytical optical model coupled with finite element analyses (FDTD) is presented. All the work has enabled OAD to develop simple two-layer anti-reflective coatings that already demonstrate high levels of transmission, superior to existing (interferential) or work in progress (Moth-eyes) AR treatments

In this study, porous conductive films were grown on glass substrates, metal substrates and nickel bowl-like array substrates by using glancing angle deposition (GLAD) of aluminum (Al), copper (Cu) and titanium (Ti). Surface morphology and structure of porous thin films were analyzed by FE-SEM and XRD, and the porosity was characterized by both reflectance and photocurrent of atomic-layer-deposited TiO2 films. The results show that the porous Al, Cu and Ti films can be prepared by GLAD, and the porosity of Al was the best of all. The porosity was found to be independent of deposition rate for films grown on substrates without rotating. As rotating the substrate, the porosity increases with increasing the deposition rate for Al films, but almost unchanged for Ti and Cu films. The porosity is independent of the rotation speed for all samples. The Ti and Cu films with low porosity can be further improved by using the nickel bowl-like arrays as the substrates. It was found that increasing the porosity improves the light trapping ability and enhance the photocurrent of coated TiO2 films.

Повний текст джерелаMit dem Ziel ein besseres Verständnis des Einflusses des Einfallswinkels in der physikalischen Gasphasenabscheidung zu erreichen, wurden experimentell realisierte und am Computer simulierte Dünnschichten untersucht. Als Abscheidetechniken kamen sowohl Elektronenstrahl-Verdampfen als auch Ionenstrahl-Zerstäubung zum Einsatz. Es wurden die Materialien Germanium, Silicium und Molybdän verwendet, die bei verschiedenen Einfallswinkeln, verschiedenen Substrattemperaturen und variiertem Restgas abgeschieden wurden. Die beobachteten Zusammenhänge, von bspw. kolumnarer Verkippung und Einfallswinkel, konnten nicht mit den etablierten Modellen in Einklang gebracht werden. Um das genaue Zusammenspiel von Abschattung und Konkurrenz-Wachstum zu verstehen, wurde eine „on-lattice“ Computersimulation entwickelt, mit dem besonderen Augenmerk auf die Vermeidung von gitterbasierten Anisotropien. Dies wurde durch Vergleich mit einer, ebenfalls entwickelten, „off-lattice“ Simulation sichergestellt. Ausgehend von den beobachteten Effekten konnte ein analytisches Modell entwickelt werden, welches die Materialeigenschaften und Abscheidebedingungen in einen einzigen Parameter vereint. Die Vorhersagen des Modells wurden an den hergestellten Schichten, den Computersimulationen und an Literaturdaten verifiziert. Abschließend werden Methoden aufgezeigt, die schräg abgeschiedenen nanostrukturierten Schichten verschiedenen Anwendungen anzupassen. Dies umfasst die in situ Dotierung von Siliciumnanostrukturen, die Erzeugung von Kern-Schale-Strukturen, sowie die biochemische Oberflächenfunktionalisierung von Silbernanostrukturen.

Surface plasmon resonance (SPR) sensing is a real-time and label-free detection technique which has the potential to benefit numerous important fields, including medical diagnostics, environmental monitoring, and food safety. However, such a sensing technique is not suited for molecular identification. On the other hand, the surface-enhanced Raman scattering (SERS) spectroscopy is a highly specific technique to identify molecules. In this study, we proposed the fabrication of multifunctional plasmonic biochips and established an optical platform to integrate plasmonic sensing and surface-enhanced Raman scattering techniques. Periodic metallic nanostructures with rough metal surfaces were made on a plastic substrate using nanoimprinting and oblique angle deposition techniques. First, the grating nanostructures with a period of 750 nm were made on a polymer film using a silicon template. An 80-nm-thick gold film was then deposited on the plastic film using the oblique angle deposition technique. The transmission spectra of the biochips with different deposition angles were measured. Transverse-magnetic polarized wave in the gold nanostructure with a deposition angle of 0° generated a sharp and asymmetric Fano resonance in transmission spectrum. It was due to the interference of broad-band cavity resonance in the grooves and narrowband surface plasmon resonance on the periodic gratings. With the increase of the deposition angle, a symmetric surface plasmon resonance instead of the Fano resonance was observed in the transmission spectrum. The observed phenomenon was attributed to the asymmetric nanostructures formed by the oblique angle deposition which destroyed the cavity resonance. We also measured the SERS spectra of para-mercaptobenzoic (pMBA) acid molecules on different plasmonic biochips. It was found that the SERS signal for the periodic nanostructure was 10 times the background SERS signal. The SERS signal increased by 6 times when the deposition angle was increased from 0° to 75°. In addition, the optical systems for measuring transmission and SERS spectra were integrated. The 785-nm laser light was normally incident on the plasmonic biochip. The reflected light and transmitted light were collected and measured by a charge-coupled device array spectrometer and Raman spectrometer, respectively. The quantification and qualification analysis of the sample can be accomplished at the same time by measuring the changes in transmitted intensity and SERS spectra. Therefore, the combination of plasmonic sensing and SERS spectroscopy provides a promising way for multifunctional chemical analysis to increase the reliability of biological detection and can benefit sensing applications.

Titanium nitride (TiN) nanostructures were fabricated by glancing angle deposition(GLAD) in direct current (DC) magnetron reactive sputtering. Slanted nanorods arrays (NRAs)was grown by controlling the substrate orientation during deposition. The impact of nitrogen flow rate relative to that of argon during deposition, and the deposition substrate temperatures of TiN were discussed. The TiN NRAs were analyzed by X-ray diffraction (XRD). The surface enhance Raman scattering (SERS) signals from Rhodamine 6G (R6G) of dropped on the substrates were detected by excited wavelength at 532nm. The influence of the length of TiN nanorods and corresponding resistivity on SERS peak intensities was investigated. In order to study the durability, the difference of variation of SERS intensity between TiN and Ag deposited NRAs with time was proposed here.

In this work, we used DC magnetron sputtering and glancing angle deposition (GLAD) to deposit titanium nitride (TiN) nanorod array on silicon wafer, glass substrate (BK7) and sapphire substrate. The surface morphology of the nanostructures was explored by changing the process parameters such as the deposition angle, post-deposition annealing, and ratio of argon-nitrogen. The morphology and the lattice orientation (111) and (200) were analyzed by SEM and X-ray diffraction (XRD), respectively. In addition, X-ray photoelectron spectroscopy (XPS) confirms its chemical analysis. The equivalent optical constants were measured by using ellipsometer. The relationship between optical constants and lattice composition was discussed and analyzed. In the experimental results, the columnar angle of the nanorods becomes larger and the column diameter becomes smaller because the proportion of nitrogen increases in the nanostructure. However, the crystallite size and the amount of nitrogen are proportional and the proportion of nitrogen increases the lattice orientation which will grow along the (200) orientation. The larger crystallite increases the porosity of the film that cause the high resistance. Thus, the porosity of the film resulting in the increase of transmission and decrease of reflection.
