摘要
The quasirelativistic INDO/1 method has been used to generate molecular orbitals for some {Ge(x)}, doped {GexGay} and {GexAsy} clusters. These one-electron energy levels predefine the density of states (DOS) and/or hole functions. The effect of the cluster size (x = 24, 56, 92) and that of dopants on the DOS profiles are discussed. The calculations are compared with those generated by periodic crystal orbitals of the EHT quality.
