title: Improvement of the photon generation efficiency in phosphorus-doped silicon nanocrystals: Γ-X mixing of the confined electron states.
abstract: It has been shown that the central-cell potential of a phosphorus ion embedded in a silicon nanocrystal effectively mixes the electronic states of X- and Γ-bands. Quantum confinement strengthens the Γ-X mixing which, in turn, straightens the nanocrystal's band structure, and substantially intensifies interband radiative recombination.
