Show affiliations


An average nuclear effective charge, deduced from atomic experimental data, is introduced to describe the electronic properties of the tetrahedrally coordinated semiconductors. Ionization potentials, energy gaps, dielectric constants, cohesive energies and heats of formation can then be calculated, for all the AIIIBV and AIIBIVC2V compounds, with an overall accuracy of the order of 7%.
