Paper Abstract

It was investigated photosensitivity of single porous silicon heterostructures. Such heterostructures were created by electrochemical anodization of silicon monocrystal substrates. An experimental investigation of porSi/Si heterostructures was connected with current-voltage characteristics and photovoltaic effects. It was observed wide band photovoltaic sensitivity from 0.4 to 1.2 micrometer for different heterostructures. Using energy band configuration it was explained obtained curves. PorSi/Si heterostructure was also high sensitive to mechanical stresses. It was concluded that heterojunction on the basis porSi/Si plates may find application as wide-band photoconverters and tenzosensitivity devices.
