Ultrabroadband density of states of amorphous In-Ga-Zn-O

Ultrabroadband density of states of amorphous In-Ga-Zn-O

The subgap density of states of amorphous indium gallium zinc oxide (a-IGZO) is obtained using the ultrabroadband photoconduction response of thin-film transistors (TFTs). Density-functional theory simulations classify the origin of the measured subgap density of states peaks as a series of donorlik...
