Identification of anomalous muonium in semiconductors as a vacancy-associated center.

Abstract

With use of a first-principles unrestricted Hartree-Fock cluster procedure, it is demonstrated that a (${\ensuremath{\mu}}^{+}{e}^{\ensuremath{-}}$) center trapped near a vacancy has all the features of the hyperfine tensors for anomalous muonium in diamond and silicon obtained from muon-spin-rotation measurements.
