Low-Energy Electron-Diffraction Study of Molybdenum (110) Surfaces

Abstract

A study of the clean and oxygen-covered molybdenum (110) surface has been carried out using low-energy electron-diffraction techniques. The clean surface is found to be the same as an ideal (110) plane in the bulk. Oxygen structures corresponding to ¼, ½, and ¾ monolayer have been found. These structures are very similar to those found for the tungsten (110) surface. Experiments on nitrogen and hydrogen adsorption are inconclusive due to interference from other residual gases (primarily carbon monoxide).
