p‐type transparent conducting oxides

The recent advance of p‐type transparent conductive oxide thin films is reviewed. The focus is on p‐type transparent oxide semiconductors CuAlO2, CuGaO2, CuInO2, SrCu2O2, and LaCuOCh (Ch = chalcogen). These materials and related device applications are then shown as examples. Room temperature operation of current injection emission from ultraviolet light‐emitting diodes based on p‐SCO/n‐ZnO p–n junctions has been demonstrated. This changed with the discovery of p‐type transparent conducting oxides, thereby opening up the possibility for all‐oxide transparent electronics. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
