ABSTRACT:
A photodetector which operates at a cryogenic temperature by utilizing superconductivity is disclosed. A plurality of mutually spaced-apart superconducting layers are formed in such a manner as to be in contact with a semiconductor layer at least one of the surfaces of which is an incidence surface of light, and means capable of accumulating carriers in the semiconductor layer is disposed.
A photodetector having high performance can thus be obtained and can be used as an interface of a system at a cryogenic temperature.
