Complex Defects in Semiconductors

Abstract

AbstractComplex defects in semiconductors are briefly reviewed, with emphasis on the electronic structure. Classes of such defects with a varying degree of complexity are discussed, with reference to recent optical data for neutral defects in GaP and silicon. These include PGa-antisite related substitutional complexes in GaP, Gai-acceptor complexes in GaP, substitu-tional chalcogen complex defects in silicon and vacancy-impurity complexes in silicon.
