New device concepts for uniformity and energy efficiency

The Source-Gated Transistor (SGT) is a type of electronic device invented at the University of Surrey.



Due to its mode of operation, the SGT has several advantages over conventional transistors, particularly in low-power, mixed-signal (analogue/digital) applications which are very cost-sensitive. We are investigating the implementation of the SGT using new materials and fabrication techniques such as inkjet printing, which would enable large-area electronic circuits to be realised with improved performance, lower energy demands and reduced cost.
