The optical and electrical properties of gallium-doped ZnO thin film with post-annealing processes of various atmospheres
Post-thermal annealing effects on grain sizes and activating Ga dopant of GaZnO Post-annealing in acetylene ambient showed the best improvement on electricity. The electron mobility increases with annealing temperature due to larger grain size. Free carrier concentrations reach saturation while annealing temperature increase.
