Shallow Trap States Control Electrical Performance of Amorphous Oxide Semiconductor Thin-Film Transistors
Måns J. Mattsson, Jinhan Lee, Christopher E. Malmberg +10
The performance of n-type amorphous oxide semiconductor thin-film transistors (TFTs) is largely controlled by the density of states (DoS) near the conduction band mobility edge. He…

Ultrabroadband Density of States of Amorphous In-Ga-Zn-O
Kyle T. Vogt, Christopher E. Malmberg, Jacob C. Buchanan +6
The sub-gap density of states of amorphous indium gallium zinc oxide (-IGZO) is obtained using the ultrabroadband photoconduction (UBPC) response of thin-film transistors (TFTs)…
