From: Band-offsets scaling of low-index Ge/native-oxide heterostructures
Ge and Ge-oxide compositions plotted as a function of oxidation time (log-scale) for (a) Ge(001), (b) Ge(110) and (c) Ge(111). In (d), the composition plots are combined to show the relative oxidation rates of the three Ge substrates, with Ge(001) being the fastest.
