Investigations of the optical and electronic effects of silicon and indium co-doping on ZnO thin films deposited by spray pyrolysis

Abstract

Silicon and indium co-doped ZnO thin films with both high optical and electrical performances have been successfully synthesised for the first time by the technique of spray pyrolysis. We find that this co-doping strategy can achieve comparable Figures-of-Merit performances to indium zinc oxide itself, but with, importantly, a significant saving in the indium content. The properties of the co-doped films are compared with those of either single indium or silicon doping.

Influence of zinc ion concentration on structure, morphology and optical properties of spray deposited ZnO thin films

“…Variety of methods has been employed for synthesis of ZnO thin films such as radio-frequency magnetron sputtering [7], chemical vapour deposition [8], and sol-gel method [9], [10] pulsed laser deposition [11]. Chemical spray pyrolysis (CSP) is an innovative technique suitable for large area thin-films deposition and very economic [12].…”
