Antimonide-based superlattice infrared barrier photodetectors Conference Paper uri icon

abstract

  • Barrier structures are now the design of high performance antimonide-based (Sb-based) cooled infrared (IR) quantum detectors. In this communication, we report on electrical and electro-optical characterizations of Ga-free and Ga-containing type-II superlattices (T2SL) photodetectors structures grown by Molecular Beam Epitaxy (MBE). Experimental measurements on Ga-free XBn and Ga-containing XBp samples were made by photo-response measurements and dark current density-voltage (J-V) characteristics performed on detectors as a function of temperature. Identification of bias voltage characteristics were extracted from measurements and resulting dark current values were compared to the state of the art of infrared technology.
