Broadband staircase quantum well infrared photodetector: working in long wavelength infrared range (LWIR)
Hoştut, Mustafa; Kartal, D.; Ergün, Yüksel; Sökmen, İsmail (Wiley-V C H Verlag GMBH, 2007)We present a theoretical investigation of a staircase-like quantum well infrared photodetector (QWIP). it detects wavelength between 7.6 mu m and 13.5 mu m range at an applied electric field of F = 1.9x10(4) V/cm at 77 K. ... -
Effect of substrate temperature on some of the optical parameters of CuInS2 films
Aksay, Sabiha; Altıokka, B. (Wiley-V C H Verlag GMBH, 2007)Polycrystalline CuInS2 films have been grown by spray pyrolysis method at different substrate temperatures, a simple method which can produce low cost and highly absorbing samples. Optical characteristics of the CuInS2 ... -
Electrical and optical properties of undoped and In-doped ZnO thin films
Çağlar, Müjdat; Çağlar, Yasemin; Ilıcan, Saliha (Wiley-V C H Verlag GMBH, 2007)Transparent conducting undoped and indium-doped zinc oxide (ZnO) thin films have been deposited by the spray pyrolysis method at 350 degrees C substrate temperature. X-ray diffraction spectra of the films have shown that ... -
Investigation of carbon produced by methane pulsed discharge
Musa, Geavit; Ekem, Naci; Akan, Tamer; Pat, Suat; Balbağ, M. Zafer; Cenik, M. İlker; Özen, Özlem (Wiley-V C H Verlag GMBH, 2007)Pulsed discharges of methane gas at atmospheric pressure were generated using high voltage power supply (20 kV-25 kHz) to produce the carbon. The pulsed discharge of methane gas was generated between two sharp wolfram ... -
Performance study of SQW GaInNAs fabry-perot lasers
Tıraş, Engin; Hepburn, C. J.; Balkan, Naci; Saarinen, M.; Pessa, M.; Jouhti, T. (Wiley-V C H Verlag GMBH, 2007)The work presented here is concerned with studies of the operational characteristics of single-quantum-well GaInNAs/GaAs Fabry-Perot lasers, where identical layer structures with differing cavity lengths are evaluated both ...
