Photodiode 1 × 64 linear array based on a double p-InAsSbP/n-InAs0.92Sb0.08/n+-InAs heterostructure

Аннотация

The results of studies of the current–voltage characteristics and of the photoelectric and luminescence properties of a monolithic diode 1 × 64 linear array based on p-InAsSbP/n-InAsSb/n⁺-InAs with the n⁺-InAs-substrate side illuminated and sensitive in the region of 4-μm are reported. An analysis is performed of the mechanisms of current flow in the temperature range of 77–353 K and also of the photosensitivity and the speed of response taking into account the spatial distribution of nonequilibrium radiation and the data of capacitance–voltage measurements.
