The thesis studies the fabrication of efficient broadband(380 nm ~ 940 nm) photodetector(PD) base on graphene/CdSe QDs/Si multiple junctions. At 2 V bias for the graphene side, the external quantum efficiency(EQE) up to 218 % at 510 nm and the responsivity as high as 0.9 A/W for the range from 520 nm to 660 nm were achieved. The response time and recovery time are 0.24 ms and 0.28 ms, respectively. Under bias of -2 V for the graphene side, the dark current, photocurrent and on/off ratio was fou- nd to be 1.77#westeur024#10-6 A, 2.06#westeur024#10-4 A and ~10+2, respectively. It was found that when CdSe QDs were added, the EQE and responsivity of graphene/CdSe QDs/Si PD with respect to that of graphene/Si PD were enhanced together with the increase in the absorption band of the detector ranging from ultraviolet to near-infrared. Thus the graphene/CdSe QDs/Si multiple junctions can form the efficient broadband phtodetector.

In this thesis, we have investigated the fundamental property of the InGaAs–capped quantum dot infrared photodetectors (QDIPs) and their applications in broadband detection and thermal imaging. Compared with standard InAs/GaAs QDIPs, InGaAs–capped QDIPs have the detection wavelength which is shifted from 6 to 7.9 μm. The results suggest that the dominant transition mechanism in the InGaAs–capped QDIPs is from the QD excited state to the InGaAs QW ground state, which reduced energy difference between the two states. By decreasing the InAs QD coverage from 2.5 to 2.0 ML, an even longer detection wavelength 10.4 μm is observed. Due to the QD excited state is pushed closer to the QW ground state in the InGaAs capping layer. With the device performance of standard and InGaAs–capped QDIPs, a straightforward approach to achieve broadband QDIPs is to stack the two structures into one device. The device would exhibit a wide detection window ranging from 4 to 11 μm with high responsivities. The phenomenon is attributed to the high responsivities of the standard QD and the InGaAs–capped QD structures in the MWIR and LWIR ranges, respectively. We bring up a simple ideal that without the complicated fabrication process, precise focusing mirror lens and readout integrated circuit (ROIC) prepare for focal plane array to extract the large–format, the thermal imaging formation can be obtained easily by a single–device scanning. It is a promising step for diagnosing diseases from a tiny cell.

The infrared absorption spectrum in midinfrared (mid IR, MIR) spectral range contains “fingerprints” of the most common molecular bonds, key to sample composition analysis and is useful for nondestructive and rapid analysis for material characterization and environment monitoring. Furthermore, the MIR light can be applied to thermal image that is corresponding spectral regime for the thermal radiation from room temperature to several hundred degrees Celcius. On the other hand, near infrared (NIR) spectral range is the regime for optical telecommunication. To sum the above, photodetectors, light sources, and thermal dissipation routes in infrared spectral range all perform the importance in various applications. However, the study in this field so far faces several problems, including processes being complicated, slow, expensive, and not compatible with silicon semiconductor process technology (Si-CMOS, Silicon-Complementary Metal-Oxide-Semiconductor). This thesis would like to develop silicon-based photodetectors working from NIR to MIR regimes, Moreover, using the broadband, high absorption of silicon-based structures to develop thermal radiation based heat dissipation structures. In the first part of this thesis, the titanium nitride (TiN) thin film coated on a deep trench silicon structure to generate low reflection and high absorption properties at resonace wavelengths. Also, TiN thin film can form a good Schottky contact with a p-Si substrate. When the resonanct wavelength at 10.6 μm, the optical absorption could be as high as 60.7%. The responsivity could be up to 0.632mV W-1 under CO2 laser (light intensity=4.26W/cm2) illumination and up to 246mV W-1 under low light intensity light source (light intensity=2.64mW/cm2). The excess voltage has great linear relationship with light intensity, and the measurement was highly repeatable. Also, the measurements were all conducted at room temperature which could satisfy the low energy comsumption demand. In the second part of this thesis, we would like to develop photodetectors working in optical telecommunication spectral range. We used back illuminated schemes of TiN thin film along with deep trench silicon structure that can perform broadband, wide angle of low reflection, and high absorption properties. The optical absorption was up to 85.7% at 1550nm wavelength. TiN thin film formed a Schottky contact with p-Si substrates and the locations which carriers generated were close to the contact surfaces. When devices conducted at zero bias, the responsivity was up to 0.412 mA W-1, and detectivity was 5.02 x109 Jones. The responsivity of the devices differed very little when the angle of incident light below 60o. In addition, we also demonstrated the photovoltage detection ability of the devices and its responsivity was 15.4mV W-1. In the the third part of this thesis, the TiN thin film and deep trench silicon structure performed broadband high absorption properties in MIR. The high absorption also represented the high emission property. By the optical measurement of practical devices, the average absorption was up to 61%. Use white light of Xe lamp along with AM1.5 filter in order to simulate solar light heating the devices. Its equilibrium temperature was lower 8.5oC than the flat film sample and the decay time constant of cooling was also 3 seconds shorter. The deeper trench, the closer the hole to period ratio (H/P) to 1/3, the lower the equilibrium temperature of the device, certificating that the high absorption conditions in simulations with lower equilibrium temperature. In the the fourth part of this thesis, we used gold (Au) thin film combined with shallow trench silicon oxide (SiO2) and successfully designed a narrow band and high emission device at specific wavelength (4.3μm), making it a high quality factor (Peak wavelength/ Full width at half maximum, Q= λ/Δλ), low energy comsumption thermal emission light source in MIR. In addition, this structure could also apply to enhance the surface enhanced infrared absorption because of its high electric field on its surface. The structure made CO2 absorption signal enhanced 5.3 times without changing the absorption peak ratio of the two peaks of CO2.

This thesis studies the fabrication of hetero-structured broadband photodetectors fabricated by the composite consisted of indium gallium zinc oxide (IGZO) incorporated with the graphene nanoflakes (GNFs) and silicon oxide (SiO2)/silicon substrate. It was found that IGZO:GNFs film along with the increase in volume concentration (0.1 ~ 0.9 vol%), the conductivity of film increases from 0.027 S / m to 0.749 S / m, which is an increase of 27.7 times. The current-voltage relation of the IGZO:GNFs/SiO2/Si devices exhibited the p-n junction characteristics. The photoresponse range comprises the UV absorption of IGZO and visible near-infrared absorption of silicon. Under negative bias of -3 V, and the illumination of light with wavelength of 350 nm (500 nm), the photocurrent of pure IGZO/ SiO2/Si diode were found to be 8.81 10 A (1.04 10 A), while the illumination of light with wavelength of 350 nm (500 nm), the photocurrent of IGZO:GNFs (0.6 vol%)/SiO2/Si diode were found to be 4.39 10 A (4.90 10 A). The corresponding responsivity for IGZO/SiO2/Si and IGZO:GNFs (0.6 vol%)/SiO2/Si were found to be 0.109 A/W (0.164 A/W) and 0.146 A/W (0.216 A/W), respectively, for illumination of 350 nm (500 nm) light. Besides, the rising times for IGZO/SiO2/Si and IGZO:GNFS/SiO2/Si devices were found to be 8.95 ms and 8.05 ms, respectively. And the the decay times for IGZO/SiO2/Si and IGZO:GNFS/SiO2/Si devices were found to be 5.83 ms and 5.48 ms, respectively. The results showed that the response times of IGZO:GNS/SiO2/Si devices become better than that of IGZO/SiO2/Si devcies. Thus, we have successfully fabricated the IGZO:GNFs/SiO2/Si hetero-structured broadband photodetectors.

In this thesis, we study gallium arsenide (GaAs) and hot electron based Schottky diode of photodetector performing broadband detection capability working from extreme ultraviolet (EUV) to near-infrared (NIR) regime. This study demonstrated the hot electrons generated in structured gold (Au) or molybdenum (Mo) electrodes and propagating to metal/ semiconductor (GaAs) junction can be used for optical-electrical signal conversion for detecting light with photon energies below the bandgap of the semiconductor, especially in the spectral regime for optical telecommunication. Furthermore, we investigated the optical properties of GaAs and metal films in the EUV spectral regime to demonstrate a low power consumption of photodetector having an ultra-broadband detection ability. In the first part of this thesis, metal (Au, Mo)/ semiconductor (GaAs) based Schottky junction photodetector has been designed for hot electron collection from deep-trench/ thin metal (DTTM) based active antenna which takes the advantage of surface plasmon resonance and three-dimensional cavity effects. The DTTM-based devices have attractive properties of low reflection and high absorption in the near-infrared (NIR) regime, which enables the GaAs based devices breaking the limitation of bandgap of 870 nm (1.42 eV), extending its detection capability to the spectral regime of optical communication wavelengths of 1310 nm and 1550 nm. Taking the Mo/GaAs DTTM device as an example, the photocurrent responsivities at 1310 nm and 1550 nm are 0.27 mA/W and 0.16 mA/W, respectively, which is an order of magnitude smaller than that of the Si-based DTTM device. However, in terms of photovoltage detection, the response of the Mo/GaAs DTTM device at 1310 nm and 1550 nm are 577.47 (V/W) and 435.15 (V/W), respectively, which is 10,000 times larger than the photoelectric response of a Si-based DTTM device. We suggested that the photovoltage responsivity is significant for the high resistance and trap density of GaAs substrate. In the second part of this thesis, the concept of backside-illuminated schemes of metal (Au or Mo) film along with GaAs based DTTM structure were proposed. Compared with the front-illuminated devices, the backside-illuminated devices have three main advantages: (1) Hot carriers could be effectively generated and effective collection. (2) Devices performed broadband absorption covering the wavelengths of 1310 nm and 1550 nm, (3) Devices performance were not sensitive to the angle of incident performing omnidirectional detection properties. The measured results demonstrated that the responsivity of photocurrent and photovoltage are much higher than those of the front-illuminated devices. In the case of Mo/GaAs DTTM device, the photocurrent responsivity of the back-illuminated type are 0.95 mA/W and 0.25 mA/W at 1310 nm and 1550 nm, respectively, and the photovoltage responsivity are 781.52 (V/W) and 540.96 (V/W), respectively. In the third part of this thesis, because of high transmission at the wavelength of 13.5 nm, we suggested Mo is a suitable metal as the front electrode of Schottky photodetectors in the EUV spectral regime. Moreover, GaAs has a high absorption coefficient compared to Si in the EUV regime. Therefore, it is considered that Mo/GaAs-based Schottky diodes have a good opportunity to be used as a superior photodetectors working in EUV regime. In this study, we extended the Mo/GaAs DTTM devices operating in the EUV regime. Because of high resistance of GaAs substrate, the generated excess photocurrent in the EUV regime is much smaller than that of the Si-based photodetector.
