New reusable optoelectronic storage medium

An investigation was made of the characteristics of switching and photosensitivity of a reusable optoelectronic storage medium based on planar metal–insulator–semiconductor–insulator–metal structures. Estimates indicate that data can be stored in such a medium with a density in excess of 10⁷ bit/cm² and the energy needed to record one bit is about 2×10^–13 J.
