Vibrational-Spectra of Oxygen on LaB6(100), LaB6(110), and LaB6(111) Surfaces - A Comparative-Study Using High-Resolution Electron-Energy-Loss Spectroscopy
The vibrational properties of the (100), (110), and (111) surfaces of LaB6 with adsorbed oxygen are compared using high resolution electron energy loss spectroscopy (HREELS). Each surface offers a distinctly different set of possible adsorption sites and at room temperature the adsorption of oxygen yields a distinctly different HREELS spectrum. However, annealing the oxygen covered surfaces to 700 degrees C produces strikingly similar results, indicating a common oxygen induced structure for the three surfaces.
