Heterojunction, Vacuum-Glass Field Effect Transistors
Published online by Cambridge University Press: 01 February 2011
Abstract
This note reports on a surface field effect transistor, SFET, where the electron channel consists of the interface between vacuum and a Cs-doped glass, and an electrode on the back of the glass substrate is used as the gate. The device has a transconductance of 4×10−10 S cm−1. The transconductance is limited by the glass surface roughness, ∼ 0.4 nm RMS. A reduction of surface roughness to 0.1 nm RMS is expected to increase device transconductance.
