ABSTRACT:
For precise selection of a cut-off wavelength of an incident light, there is disclosed an optoelectric transducer operative to produce an electric charges on the basis of an incident light, comprising, (a) a carrier injected region with a first conductivity type formed of a non-degenerative semiconductor material and having a surface capable of being illuminated by the incident light, (b) a potential-barrier region, a first homojunction being formed between the carrier injected region and the potential-barrier region, and (c) a photoelectric converting region with the first conductivity type formed of a degenerative semiconductor material, a second homojunction being formed between the potential-barrier region and the photoelectric converting region, wherein a potential barrier is formed at the second homojunction between the potential-barrier region and the photoelectric converting region, so that it is possible to form the potential-barrier with a arbitrary height by selecting the two semiconductor materials for the potential-barrier region and the photoelectric converting region.
