摘要：
The electronic structure and surface properties of gamma-Al2O3 thin films are studied. We have prepared the films by oxidizing Al foils under controlled conditions and we characterize the gamma-Al2O3 samples by means of XPS, UPS, and TEM and found no charging. Pronounced effects in temperature-dependent changes of the work function are observed which result from changes in band bending and electron affinities by reorganisation and migration of defects. Thereby the ability of these systems for prototype studies in catalysis and analysis of defects is demonstrated,
