Atomic bonding and electrical characteristics of metallic and semi-metallic elements

Abstract

In this paper, we use density functional theory to calculate the electronic structure and properties of 46 metallic and semi-metallic elements. The binding energy and bond charge model (BBC) model is combined with the tight binding and density functional tight binding approaches to obtain quantitative information about atomic bonding at the atomic scale and to understand the contributions and effects of deformation energy density, energy shifts, and atomic bonding on the Hamiltonian.
