Abstract: | A numerical study of the dependence of the space-charge density Qsc on the surface potential Ψs in a two-dimensional electron inversion layer on Si(100) is presented. The dependence Qsc(Ψ)s being a macroscopic characteristic of semiconductor space-charge layers is found to be considerably influenced by the surface quantization in a wide temperature range up to room temperature. The conditions for the appearance of appreciable differences in the behaviour of the Qsc(Ψ)s curves in the quantum-mechanical and quasi-classical cases are determined and discussed. |
