Self-consistent pseudopotential calculation of the electronic properties of the InP (110) surface

Abstract
Self-consistent pseudopotential calculations for InP (110) surface have been carried out using the repeated slab method and assuming a relaxed surface geometry. Various surface states have been found and their character and symmetry properties have been investigated by analysing the corresponding pseudocharge density maps. Comparison between self-consistent and non-self-consistent calculations show significant differences both in the number and in the energy location of the surface states. The results are in agreement with the experimental findings obtained by different spectroscopical techniques.
