Abstract

The interaction of oxygen with the (310) surface of LaB[subscript 6] has been investigated using Auger electron spectroscopy and mass spectrometric analysis. Measurements were made on both preadsorbed layers of oxygen and in fixed oxygen pressures. Desorption products observed were BO, B2O2, B2O3, and LaO. Oxygen saturation of the surface at room temperature was observed with adsorptions of 50L. Oxides on the surface appear as B2O3 and an unidentified lanthanum bearing oxide. Temperature and pressure dependencies of the desorption products were studied in detail. Faceting [sic Facetting] of the surface into (100) planes was observed.
