Highly Sensitive Light-induced Memory Effect with Amorphous Se-SnO(2) Heterojunction
Abstract:
The light-induced memory effect in amorphous selenium films is studied by fabricating them into a sort of heterojunction (Se-SnO(2)) so as to be able to apply the bias voltage together with the laser beam irradiation for memory. Under the reverse bias voltage, a region of high electric field is formed in the selenium film near the junction. Remarkable enhancement in the photo-induced image spot is achieved if an appropriate bias voltage is applied simultaneously, indicating the sensitization of the memory effect due to the photocurrent induced by the high electric field in the selenium film.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The semiconductor's...
