Band offsets between SiO2 and phase change materials in the (GeTe)x(Sb2Te3)1−x pseudobinary system

The energy band alignment between stoichiometric phase change alloys residing along the pseudobinary line of GeTe–Sb2Te3[(GeTe)x(Sb2Te3)1−x] and SiO2 was obtained employing high-resolution x-ray photoelectron spectroscopy. The valence band offsets were determined using both the core-level spectra an...
