Broadband asymmetric quantum-well infrared photodetector in long-wavelength infrared range (LWIR)
Hostut, M.; Ergun, Y.; Sokmen, I. (IEEE, 2007)A theoretical investigation of a GaAs-AlGaAs infrared detector consisting of three asymmetric quantum wells is presented. Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 pro, ... -
Broadband staircase quantum well infrared photodetector with low dark current
Ergun, Y.; Hostut, M.; Eker, S. U.; Sokmen, I. (ELSEVIER SCIENCE BV, 2006)We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). It detects wavelengths between 8.8 mu m and 12.3 mu m at an applied electric field of F= 6 x 10(4) V/cm at room ... -
Broadband staircase quantum well infrared photodetector: working in long wavelength infrared range (LWIR)
Hostut, M.; Kartal, D.; Ergun, Y.; Sokmen, I. (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. ... -
Electrical performance of InAs/AlSb/GaSb superlattice photodetectors
Tansel, T.; Hostut, M.; Elagoz, S.; Kilic, A.; Ergun, Y.; Aydinli, A. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)Temperature dependence of dark current measurements is an efficient way to verify the quality of an infrared detector. Low dark current density values are needed for high performance detector applications. Identification ... -
The investigation of quantum efficiency constituents of InAs/AlSb/GaSb based N structure type-II SL photodetectors with InAlAs interface
Kilic, A.; Tansel, T.; Hostut, M.; Elagoz, S.; Ergun, Y. (IOP PUBLISHING LTD, 2018)We report on the optical properties of InAs/AlSb/GaSb based Type-II superlattice N-structure with p on n configuration. The detector structure is designed to operate in the mid wavelength infrared range with 50% cut-off ... -
