The thickness of HfO2 and hafnium silicate HfxSi1 − xOy thin films with a range of compositions are investigated using three complementary analytical techniques. We compare results obtained from Medium Energy Ion Scattering spectroscopy, spectroellipsometry and high-resolution Transmission Electron Microscopy. Our results demonstrate that the thickness of the silicate layers decreases with the Hf content
