Frontier of transparent conductive oxide thin films

The recent advancement of transparent conductive oxide thin films is reviewed using our strategy. Topics focused are the lowest resistive indium tin oxide films, deep-ultraviolet (deep-UV) transparent conductive oxides (TCO) thin film, p-n homo junction based on bipolar CuInO2, and UV-light emitting diode based on p-n hetero-junction. A frontier of transparent oxide semiconductors is opening as a consequence of discovery of p-type TCO. (C) 2002 Elsevier Science Ltd. All rights reserved.
