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 ... -
Low dark current N structure superlattice MWIR photodetectors
Salihoğlu, Ömer; Muti, Abdullah; Turan, Raşit; Ergün, Yüksel; Aydınlı, Atilla (Spie-Int Soc Optical Engineering, 2014)Commercially available read out integrated circuits (ROICs) require the FPA to have high dynamic resistance area product at zero bias (R(0)A) which is directly related to dark current of the detector. Dark current arises ...
