Strained layer InGaAs channel negative-resistance field-effect transistor

Abstract
We report experimental results on a negative-resistance field-effect transistor (NERFET), grown by metalorganic chemical vapor deposition, which incorporates a strained In0.18Ga0.82As channel layer adjacent to the barrier. The thin InGaAs layer provides higher mobility and enhanced carrier confinement for the channel electrons. This device structure yields a significant increase in the drain current peak-to-valley ratio over comparable GaAs-AlGaAs NERFETs.
