By investigating the effect of target temperature (TG) on electrical and optical properties, the origin of electrical conduction is verified as the effect of the high TG, which enhances crystal quality that provides higher mobility of electrons as well as more effective activation for the Al dopants. The optical bandgap increases from 3.30 eV for insulating ZnO to 3.77 eV for conducting AZO grown at high T G, and is associated with conduction-band filling up to 1.13 eV due to the Burstein-Moss effect. © 2013 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/82627||ISSN:||00036951||DOI:||10.1063/1.4795763|
