Model Pseudopotential Calculations of the Electronic and Bonding Properties of Group-IV Elements

Abstract
We have calculated the band structure and electronic charge densities as a function of position in the unit cell for several two-parameter pseudopotential models for group-IV elements. This was done in an attempt to understand the relationship between charge density and band structure in crystalline diamond-structure semiconductors. We have found that by changing only one parameter in the pseudopotential we can simulate the properties of the group-IV semiconductors.
