Abstract

In this paper, a subnanometer characterization of the Ga2O3/GdGaO dielectric gate stack grown on top of InGaAs lattice matched to n(+) InP substrate is presented. The paper shows the analysis of two samples grown using different substrate temperature. This clearly affects the electrical characteristics as well as the photoluminescence properties. The paper also describes how the growth conditions of oxide stack affect the elemental distribution across the interface region.
