A modified form of the polar model of crystals
A model for the description of materials with narrow energy bands is proposed. It is shown that in narrow-band materials an electron-hole symmetry is absent in contrast to the Hubbard model. In this paper a metal-insulator transition is studied. The obtained results are compared with the experime...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A model for the description of materials with narrow energy bands is proposed.
It is shown that in narrow-band materials an electron-hole symmetry
is absent in contrast to the Hubbard model. In this paper a metal-insulator
transition is studied. The obtained results are compared with the experimental
data for narrow-band materials. Some specific narrow-band effects
are discussed. |
