Copper (II) Oxide Semiconductors

Description. Copper (II) oxide is a higher oxide of copper and belongs to the monoclinic crystal system. It occurs as a black solid with an ionic structure that melts above 1200°C with some loss of oxygen. It is an irritant, and causes damage to the central nervous system and endocrine system. It can be formed by heating copper in air.
