摘要: Using electron energy-loss spectroscopy, the oxygen K-edge excitation in a range of crystalline standards relevant to candidate high-k materials has been examined. The spectra have modeled using electronic structure calculations order understand influence local coordination environment on data. knowledge obtained is used probe atomic thin amorphous films “HfSiO.”
