Microscopic Mechanisms of Self-compensation in Si d-doped GaAs

We combined systematic cross-sectional scanning tunneling microscopy and spectroscopy investigations with Hall measurements on single Si δ-doped layers, as well as Si δ-doped superlattices in GaAs. We found that Si self-compensation involves nucleation and growth of electrically neutral Si precipitates at the expense of the conventional donor Si phase.

Abstract: We combined systematic cross-sectional scanning tunneling microscopy and spectroscopy investigations with Hall measurements on single Si δ-doped layers, as well as Si δ-doped superlattices in GaAs. We found that Si self-compensation involves nucleation and growth of electrically neutral Si precipitates at the expense of the conventional donor Si phase.
