摘要
Blueshift of the hand gap due to quantum confinement is calculated in a tight-binding model for a series of nine III-V zinc-blende AB (A=Al, Ga, or In, B=As, P, or Sb) and two diamond group-IV (Si and Ge) semiconductor clusters. Analytic expressions for the highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels are given as a function of the cluster size. Comparison is made to results obtained by the pseudopotential method and to experimental results. (C) 2000 American Institute of Physics. [S0003-6951(00)00431-9].
