Abstract

Abstract The energies of low-energy defects in tetrahedrally coordinated, pnictide, and chalcogenide amorphous semiconductors are estimated. Both nonintimate and intimate charged pairs are considered. The sign and value of the effective correlation energy is estimated in each case and the variation of the Fermi energy with electronic correlation is calculated. Although the Fermi energy is storngly pinned for nonintimate pairs with a negative effective correlation energy, it unpins when the pairs are intimate.
