Electrical and optical performance of InAs / AlSb / GaSb superlattice photodetector
(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
(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
(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 ... -
Low dark current N structure superlattice MWIR photodetectors
(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 ...
