摘要: Amorphous thin films of In-Ga-Zn-O (a-IGZO) doped with Mo have been fabricated by using magnetron co-sputtering technique. The Mo concentration in a-IGZO films was modulated by varying the sputtering power applied on the Mo target. The electrical, optical and magnetic properties of Mo-doped a-IGZO films grown on glasses were investigated. The carrier density and mobility of a-IGZO films can be remarkably enhanced by low concentration Mo doping. On the other hand, the optical bandgap of a-IGZO films is not significantly affected by Mo doping. However, the transmission is decreased with increasing the Mo doping. Moreover, all Mo-doped films exhibit room-temperature ferromagnetism. (C) 2012 Elsevier Ltd. All rights reserved.
