Electrical and optical performance of InAs / AlSb / GaSb superlattice photodetector
Hoştut, M.; Tansel, Tunay; Ergün, Yüksel; Kılıç, A.; Aydınlı, A. (TANGER Ltd., 2015)We report on electrical and optical performance of InAs/AlSb/GaSb type-II superlattice photodetectors. The detector structure is designed to operate in the MWIR domain with a cut-off wavelength of 4.3 µm at 125 K. The ... -
Electronic and optical properties of 4.2 mu m"N" structured superlattice MWIR photodetectors
Salihoğlu, Ömer; Hoştut, Mustafa; Tansel, Tunay; Kutluer, K.; Kılıç, A.; Alyörük, M.; Aydınlı, A. (Elsevier Science BV, 2013)We report on the development of a new structure for type II superlattice photodiodes that we call the "N" design. In this new design, we insert an electron barrier between InAs and GaSb in the growth direction. The barrier ... -
Gibbs Free Energy Assisted Passivation Layers
Salihoğlu, Ömer; Tansel, Tunay; Hoştut, M.; Ergün, Y.; Aydınlı, Atilla (Spie-Int Soc Optical Engineering, 2016)Reduction of surface leakage is a major challenge in most photodetectors that requires the elimination of surface oxides on etched mesas during passivation. Engineering the passivation requires close attention to chemical ... -
High quantum efficiency Type-II superlattice N-structure photodetectors with thin intrinsic layers
Ergün, Yüksel; Hoştut, Mustafa; Tansel, Tunay; Muti, Abdullah; Kılıç, Abidin; Turan, Raşit; Aydınlı, Atilla (Spie-Int Soc Optical Engineering, 2013)We report on the development of InAs/AlSb/GaSb based N-structure superlattice pin photodiode. In this new design, AlSb layer in between InAs and GaSb layers acts as an electron barrier that pushes electron and hole wave ...
