摘要：
The occurence of confinement effects for amorphous Si and Si:H clusters is investigated theoretically in an empirical tight binding treatment. The results show that one must consider three categories of states: strongly localized, weakly localized and delocalized. In all cases a substantial blue shift with reduction in size is obtained, of comparable magnitude for amorphous a-Si:H and crystalline clusters. These results are compared with available experimental data.
