Variational approach to the problem of energy spectrum of surface electrons over liquid-helium film
The energies of first two subbands are calculated, within a variational approach, for electrons localized over the surface of a liquid-helium film covering a solid substrate. The results are obtained for arbitrary value of the dielectric constant of the solid substrate, covering both the limit of...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The energies of first two subbands are calculated, within a variational approach, for electrons
localized over the surface of a liquid-helium film covering a solid substrate. The results are obtained
for arbitrary value of the dielectric constant of the solid substrate, covering both the limit
of a substrate with a dielectric constant close to unity (such as a rare gas solid) and a metal. The
results for the subband energies for a metallic substrate are compared with those obtained previously
by a different method by Gabovich, Ilchenko, and Pashitskii. The agreement is rather good
supporting the applicability of the variational method for calculating the energy spectrum of surface
electrons in a wide range of substrate parameters. |
