Transmission electron microscopy and X-ray photoelectron spectroscopy depth profile analysis have shown that the films have an oxidized surface layer which has an influence on the optical model of the films derived from ellipsometric data.

The surface of the films obtained is quite smooth; the arithmetic average roughness does not exceed 2 nm.
