Zinc oxide-based conductor
View Patent ↗A zinc oxide-based conductor includes ZnO co-doped with gallium and manganese. Preferably, the doping concentration of the gallium ranges from 0.01 at % to 10 at % and the doping concentration of the manganese ranges from 0.01 at % to 5 at %. More preferably, the doping concentration of the gallium ranges from 2 at % to 8 at % and the doping concentration of the manganese ranges from 0.1 at % to 2 at %. Still more preferably, the doping concentration of the gallium ranges from 4 at % to 6 at % and the doping concentration of the manganese ranges from 0.2 at % to 1.5 at %. The zinc oxide-based conductor is a transparent conductor that is used as an electrode of a solar cell or a liquid crystal display.
