We study the mechanisms of photocurrent generation in the SiGe/Si heterojunction internal photoemission (HIP) infrared photodetectors and present a qualitative model. It has been shown that the performance of our devices depends significantly on the applied bias and the operating temperature. The device presented here allows us to tune the cut-off wavelength between 28.3 mum and 17.8 mum by changing the potential difference across the device.

Investigation of photovoltaic properties of amorphous InSe thin film based Schottky devices Yilmaz, K.; Parlak, Mehmet; Ercelebi, C. (IOP Publishing, 2007-12-01) In this study, device behavior of amorphous InSe thin films was investigated through I-V, C-V and spectral response measurements onto SnO2/p-InSe/metal Schottky diode structures. Various metal contacts such as Ag, Au, Al, In and C were deposited onto amorphous p-InSe films by the thermal evaporation technique. The best rectifying contact was obtained in a SnO2/p-InSe/Ag Schottky structure from I-V measurements, while the Au contact had poor rectification. Other metal contacts (Al, In and C) showed almost oh...
Lattice-matched AlInAs-InGaAs mid-wavelength infrared QWIPs: characteristics and focal plane array performance Kaldirim, M.; Arslan, Y.; Eker, S. U.; Beşikci, Cengiz (IOP Publishing, 2008-08-01) The AlInAs/InGaAs material system is promising for mid-wavelength infrared (MWIR) and multi-band quantum well infrared photodetectors (QWIPs) as a lattice-matched alternative to the strained AlGaAs/InGaAs system. In this paper, we report a large format (640 x 512) AlInAs/InGaAs QWIP focal plane array (FPA) with 4.9 mu m cut-off wavelength and assess the performance of this material system for MWIR QWIP applications at both pixel and large format FPA level. We also experimentally demonstrate that the cut-off...
Characterization of GZO thin films fabricated by RF magnetron sputtering method and electrical properties of In/GZO/Si/Al diode Surucu, O. Bayrakli (Springer Science and Business Media LLC, 2019-11-01) The main focus of this work is the structural and optical characterization of Ga-doped ZnO (GZO) thin film and determination of the device behavior of In/GZO/Si/Al diode. GZO thin films were deposited by RF magnetron sputtering technique from single target. The structural and morphological properties of GZO film were investigated by X-ray diffraction (XRD), Raman scattering, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy analysis (EDS) measurements. Optical properties of the fil...
Effects of tail states on the conduction mechanisms in silicon carbide thin films with high carbon content SEL, KIVANÇ; AKAOĞLU, BARIŞ; Atilgan, Ismail; Katircioglu, Bayram (Elsevier BV, 2011-03-01) Hydrogenated amorphous silicon carbide (a-SiCx:H) films of different carbon content (x) were deposited by radio frequency plasma enhanced chemical vapor deposition (PECVD) system. Apart from the X-ray photoelectron spectroscopy (XPS) and UV-Visible transmission analyses, the resistivity measurements between 293 K and 450 K were emphasized to assess the eventual transport mechanisms. The film resistivities are unexpectedly found relatively low, especially for high carbon content. In the frame of exclusive ba...
Characteristics of HfO2 and SiO2 on p-type silicon wafers using terahertz spectroscopy Altan, Hakan; Pham, D.; Grebel, H.; Federici, J. F. (IOP Publishing, 2007-05-01) The effect of high-kappa dielectric HfO2 films on 200 mm diameter p-type silicon substrates was investigated and compared with conventional dielectric material, SiO2. We employed all-optical characterization methods using terahertz (THz) time-domain spectroscopy and visible cw pump/THz probe spectroscopy. Measurements were performed on two sets of samples, each set containing both HfO2 and SiO2 coated wafers with varying thickness of oxide layer. One set had a protective coating of either photoresist or Si3...
