Surface defects and core excitons at the (2×1) asymmetric-dimer (100) surface of Si Academic Article uri icon


  • Predictions are given for the chemical trends in (i) deep energy levels associated with 28 sp3- bonded substitutional defects, and (ii) energies of Hjalmarson-Frenkel core excitons at the (100) surface of Si, reconstructed according to Chadi's (2×1) asymmetric-dimer model. The predictions suggest that P at this surface should produce a deep level, and that the Hjalmarson-Frenkel surface core exciton should have a binding energy that is strongly site dependent. © 1984 The American Physical Society.
