Abstract
Pseudocharge densities on (110) GaAs obtained by self-consistent pseudopotential methods are compared with atomic charge densities and experimental information. Considerable disagreement is found and possible reasons are considered. It is concluded that current pseudocharge densities may not provide an accurate representation of the charge density at the surface.Keywords
