Abstract
A thin film has a band gap of 2.2 eV or more and in which a crystal includes an atomic vacancy and an electron, a microwave irradiation system configured to irradiate the thin film with a microwave in response to driving from outside, an excitation unit configured to excite the electron included in the thin film in response to driving from outside, and a detector configured to detect, as an electric signal, at least either one of an intensity of light outputted from the thin film when the electron transitions from an excited state to a ground state and a change in conductivity of the thin film based on excitation.
