A semiempirical approach to the evaluation of corrections to LDA electronic states and effective masses in semiconductors is described. Applications to GaAs, AlAs, Ge, Ga1-xAlxAs VCA alloys are presented, and a scaling law for the scissor operator is discussed.

Abstract
A semiempirical approach to the evaluation of corrections to LDA electronic states and effective masses in semiconductors is described. Applications to GaAs, AlAs, Ge, Ga1-xAlxAs VCA alloys are presented, and a scaling law for the scissor operator is discussed.
