Effects of Uniaxial Stress on the Luminescence Lines Due to Multiexciton Complexes Bound to Phosphorus in Silicon

Abstract
We report the results of high-resolution studies of the effect of uniaxial stress on the bound-multiexciton-complex luminescence lines in phosphorus-doped silicon. Our results differ significantly from those contained in two previous studies which attempted to rule out the bound-multiexciton-complex explanation of these lines, and instead strongly support Kirczenow's shell model of the structure of the bound-multiexciton complexes. In addition, new lines are observed which are interpreted as stress-induced two-electron transitions of the bound exciton.
