| 摘要 | The local electronic structure of intrinsic defects, including antisites, interstitials, vacancies and complexes with themselves or with Si impurities, in a (GaP)1/(lnP)1 (001) strained-layer superlattice determined by the Keating model, is calculated using a developed recursion method. Besides the localized states obtained, attention is paid to the electronic occupancy on various defects. A general consequence of describing the influence of isolated defects on the electron distribution of their neighbours is given. It is found that the charged state of an atom will be changed when it becomes an antisite. A closely bound (I(p)-P(III)) (III - Ga or In) pair, formed by coulombic interaction, will induce some states in energy gap. No evidence is found anywhere of Et-2-like behaviour in this system. Some novel diffusion mechanisms, based on I(p) and V(p) complex formation and dissociation, are presented. |
