Abstract

A transferable orthogonal tight-binding model for molybdenum is developed which goes beyond the traditional two-center approximation. The elements of the Hamiltonian matrix as well as the repulsive potential are allowed to depend on the environment. Several bulk, atomic defect and surface properties are calculated and compared with ab-initio data and experimental results to check the accuracy of the model.
