Abstract
Incorporation of a boundary condition into the Thomas‐Fermi approximation is generalized for systems with finite surface barriers. The standard and the modified procedures for the determination of the charge density are tested on the image‐type model potential corresponding to the bent bands at surfaces of semimetals or highly doped semiconductors. Substantial improvement of the description of the electron charge density is achieved in the modified Thomas‐Fermi approximation.
