1. A method for fabricating a thin-film transistor (TFT), comprising the steps of:

  • a) providing a substrate,b) depositing and patterning a metal gate adapted to be anodized,c) anodizing the patterned metal gate to form a gate dielectric on the metal gate,d) depositing and patterning a channel layer comprising a multi-cation oxide inorganic material over at least a portion of the gate dielectric, ande) depositing and patterning a conductive source and conductive drain spaced apart from each other and disposed in contact with the channel layer.
