New insights into the design of contact-controlled thin-film transistors
Contact-controlled “source-gated” transistors now have a two-decade history. Important advances have been made early on into the understanding of their operation and routes to performance improvement. In recent years, however, new architectural advances and means of exploiting the feedback loop between the properties of the rectifying source contact, semiconductor and insulator have led to a new generation of devices which address the historical limitations of such structures. In this talk, we review the operation of contact controlled transistors and describe their most promising applications in numerous thin-film material systems, with direct reference to newly found understanding.
