Abstract
The interaction of oxygen with a tantalum surface has been studied in an ultra high vacuum system. This study consisted of observing the thermal desorption of neutral species from the surface and the effects of gas adsorption on the electron work function. The study of the thermal desorption spectrum revealed the presence of two adsorbed gas species. From this study, the initial coverage of each adsorbed species and the order, heat of activation, change in entropy and free energy change for each of the desorption reactions were ascertained. The effect of the adsorption of oxygen on the tantalum surface was observed from the change in the electron work function. The electron work function in these studies was determined by a contact potential difference methods.
