Head Chuiko Gennady, Registration Date 01-11-2007 Organization Kherson national technical university popup.description2 There have been explained the peculiarities of the density of states and also of the effective masses in their dependence on the topology of the surfaces of equal energies as for the semiconductors of АIIBV class (Cd3As2, Zn3As2, Cd3P2, Zn3P2). The geometrical approach for the calculations of the densities of states has been proposed and examined. There have been proposed thereto the models of the influence of the lattice deformation on the energy spectra of crystals either with or without the symmetry centre. The Hamiltonian of the Harrison's type has been obtained as well as its partly diagonal form. Product Description popup.authors popup.nrat_date 2020-04-02 Close
