    • The present invention relates to a semiconductor photoelectric device including a InAs layer formed to monoatomic thickness sandwiched between spacer layers adjacent to an emitter to maximize a difference in energy between two quantum states in accumulation layer of a resonant tunneling diode having a double barrier structure, resulting in separating the resonant tunneling current determined by two quantum states of the triangular well in accumulation layer of resonant tunneling diode, even when light of a low intensity is irradiated to the surface of the resonant tunneling diode. Thus, there is provided an optical controlled resonant tunneling diode, making it possible to manufacturing a switching device for controlling an electric signal using light source by adjusting, using light, the resonant tunneling determined by an excited state of the triangular well.
