Vertical InAs Nanowire Wrap Gate Transistors on Si Substrates

Abstract

We report on InAs enhancement-mode field-effect transistors integrated directly on Si substrates. The transistors consist of vertical InAs nanowires, grown on Si substrates without the use of metal seed particles, and they are processed with a 50-nm-long metal wrap gate and high-kappa gate dielectric. Device characteristics showing enhancement-mode… (More)
