Comment:

The oxide was formed using a constant flow of 101325 Pa of O2 at 623 K for 2 h. The intensity ratio of As(V)/As(III) components was 0.56. The oxide thickness measured by ellipsometry was 34 A. The interfacial As layer thickness was 6.4 A. The chemical shift is relative to the substrate atoms.
