摘要
Empirical pseudopotential plane wave theory is used to study the electronic and optical properties of thousand atom hydrogen passivated Si quantum dots, wires and films. The properties studied include: (1) band gap vs. size; (2) band gap vs. shape; (3) total electronic density of state and optical absorption spectra: (4) dielectric constant vs. size. The results are compared with tight binding and other model calculations. Comparison with recent experimental data is discussed.
