The structural change from the metastable state in amorphous chalcogenides has been a long-standing research topic. We have found that the optical transmittance of In-Se evaporated films, which are mainly composed of amorphous phase, increases over a long period of time of more than one year at room temperature. The mechanism of the metastable state and long-term structural change in In-Se evaporated films is investigated.
