Abstract Aluminum oxide deposited on a clean rhenium field emission microscope tip at room temperature starts to migrate on the metal surface at about 600° C. Various face specific layer formations occur above this temperature. They either increase or decrease the local electron emission. Complete desorption of the aluminum oxide is obtained at about 1350°C. The remaining oxygen can be removed by heating at 1900°C. Average work function changes are discussed together with the corresponding FEM patterns of the various adsorption stages. Comparisons are made with the adsorption system aluminum oxide on tungsten.
