摘要: The close contact between theory and experiment in semiconductor surface studies has shaped the form of recent theoretical to a large extent. As result, these have concentrated on specific substrate surfaces adsorbates, with little attention “generalized” models. systems were typically chosen bases simplicity experimental accessibility. These criteria led concentration low index surfaces, ordered adsorbed layers simple unit cells. Since independent-electron models, correlation treated an averaged way [3.1,2] proven adequate interpret experiment, there been work specifically many-body effects [3.3].
