Chemical-Vapor Deposition Of Cd1-xMnxTe

Experimental process makes films with interesting magnetic and magneto-optical properties. Films of dilute magnetic semiconductor alloy Cd1-xMnxTe deposited on glass and GaAs substrates by metalorganic chemical-vapor deposition (MOCVD). Devices made with Cd1-xMnxTe films known to exhibit strong photoluminescence, stimulated emission, and magnetically-tunable lasing action. In addition, energy-band gaps of such material tailored by altering its composition - property giving flexibility in development of high-efficiency cascade solar photovoltaic cells. Performs at atmospheric pressure, resulting in more-uniform films, covering larger area, and enabling higher production rate.
