Defect States in Tetrahedral Amorphous Semiconductors

  • J. C. Knights

The issue of defect states in tetrahedral amorphous semiconductors is addressed from both structural and electronic viewpoints. Extended structural inhomogeneities are identified as the principal structural defects while localized dangling bonds are the principal electronic defects. Correlations between the two in the specific case of a—Si:H are discussed in detail and the issue of the interrelationship between defects and impurities described.
