Effects of a High-k Dielectric on the Performance of III–V Ballistic Deflection Transistors

Abstract

This letter presents a first successful integration of a high-k dielectric, i.e., Al2O3, with III-V semiconductors in ballistic deflection transistors (BDTs). The Al2O3 is deposited using atomic layer deposition, which allows the formation of uniform layers along the walls of etched trenches. The BDT transfer characteristic shows strong dependence on the… (More)
