摘要
In this paper a quantitative determination of the elemental distributions across a similar to 10 nm Ga(2)O(3)/GdGaO layer with Pt metal gate cap on top of an InGaAs/AlGaAs/GaAs substrate is presented. Some effects of annealing on the elemental distribution across the Ga(2)As/Ga(2)O(3)GGaO oxide layer are described. The paper also discusses the analysis of the interface GaAs/Ga(2)O(3)/GGO at a sub-nm level by high-resolution HAADF STEM imaging. (C )2008 Elsevier B.V. All rights reserved
