InSb PHOTODIODES (REVIEW. PART III)

Summarized have been literature data on the main parameters of defects in InSb, namely: ionization energy, concentration and capture cross section. The main recombination mechanisms of non-equilibrium charge carriers in monocrystalline InSb have been considered. The role of antistructural defects in the mechanism of Schockley–Read–Hall recombination has been analyzed. The mechanisms of charge carrier transfer and threshold parameters of InSb infrared photodiodes have been analyzed. The mechanisms of conductivity of InSb MOS structures have been described. The energy of the traps in the anodic oxide, which can define the mechanism of Poole–Frenkel emission, has been determined. The results of thermal cycling of MOS structures based on InSb have been presented.

Keywords: InSb photodiode, MOS structures, defects, recombination mechanisms, inhomogeneous p-n junction.
