Transparent conducting Ga‐doped ZnO thin film for flat‐panel displays with a sol‐gel spin coating

Abstract A novel non‐alkoxide sol‐gel process for synthesizing Ga‐doped ZnO thin film on glass was derived for possible use as a transparent electrode in flat‐panel displays, using zinc acetate dehydrate as the starting material. The structural and electrical properties of thin films have been characterized as functions of Ga addition and post‐heat‐treatments. Their carrier density, Hall mobility, and optical transmittance were measured and discussed herein to explain the characteristics of the sol‐gel‐derived Ga‐doped ZnO thin film on glass.
