  • Semiconductor optoelectro transducer
    Patent number: 4641167
    Abstract: A semiconductor optoelectro transducer is highly sensitive in infrared to far infrared regions and is operable at high speed. To this end, the optoelectro transducer is formed by a static induction transistor or a static induction thyristor and an element which are excited by light of longer wavelength than that of light corresponding to the energy of the energy gap of a channel region, is added to the channel region which receives light.
