Abstract

We use the self-consistent pseudopotential method with a supercell model of a-Si:H to study the electronic structures of substitutional fourfold- coordinated P and fourfold-coordinated B at the second neighbor of a dangling bond. Partial transfer of charge from the impurity state to the dangling bond state is examined. The influence of passivating the dangling bond by a single H atom on the impurity state is also discussed.
