摘要： An infrared light detector with an infrared light sensitivity thereof further improved. According to the infrared light detector, an isolated region of a first electronic layer is switched between a “disconnected status” and a “connected status”. Under the connected status, saturation of an electrostatic charge quantity of the isolated region in the disconnected status is eliminated, and consequently, saturation of a variation amount of an electrical conductivity of a second electronic layer is eliminated. Therefore, the infrared light sensitivity is further improved by time integration of the variation amount of the electrical conductivity of the second electronic layer.

摘要： An infrared photodetector that is capable of efficiently detecting single photon over an extensive range of wavelengths from several μm to several hundreds of μm and is suitable for arraying, and wherein an oscillatory electric field of a single infrared photon (37) parallel to a plane of the patch section (36) of a microstrip antenna when the photon is incident to cause the latter to resonate therewith is converted to an oscillatory electric field (38z) in a z direction, which an electron (39) in a quantum dot (24a) in its base state subband (30) is allowed to absorb, thereby being excited to a first excitation state subband (31) to tunnel through a potential barrier (32) and set free to escape into a quantum well (26) in a −z direction where it is absorbed. An electric field by ionization of the quantum dot (24a) as a result of escape of the electron (39) causes change in conductance of a point contact (26e). An ionized state continuing long, the integral of change in current (42) flowing from a source (26a) to a drain (26b) becomes a magnitude that can be detected, and sensitivity that allows detecting a single infrared photon is achieved.
