A new type of total-energy functional for semiconductors is proposed, using a form based on an approximate quantum-mecahnical analysis. Two new types of terms are included: pair terms giving a matrix description of an atoms local environment, and cluster terms describing the ring topology. The scheme reproduces both the covalent and metallic behavior of semiconductor materials in the appropriate limits. A parametrized form of the scheme is applied to Si.
