AbstractA linear response of the electron system of multilayer conducting structures placed in a strong magnetic field to an external action in the form of an electric field and a temperature gradient is studied theoretically. It is shown that joint investigations of the magnetoresistance and the thermo-emf allows new important information on the structure of the electron energy spectrum to be obtained and the presence of Q1D sheets of the Fermi surface to be revealed.

Different Characteristics

In this paper we study the electron energy spectrum corresponding to Landau levels in doped graphene when an external magnetic field is applied in the direction normal to the graphene planar sheet. The derived dispersion relation for the electrons in the doped graphene allows us to determine the dependence of the electrical conductivity on the applied magnetic field. This relationship between electrical conductivity and applied magnetic field is further analyzed for different characteristics of the impurities; specifically the potential of hybridization and the energy of the adsorbed atom.

AbstractWe have studied the Rashba spin-orbital effect on a diluted magnetic semiconductor (DMS) quantum well with parabolic potential in the presence of a magnetic field parallel to the z axis, taking into account the Zeeman coupling and the s-d exchange interaction between the carriers and the magnetic ions. We have obtained an analytical expression for the electron energy spectrum, which depends on the magnetic ion concentration, temperature, and strength of magnetic field. By using the obtained energy spectrum, we calculated the electron effective g*-factor. We have found that effective g*-factor increases when the magnetic field increases; by increasing the strength of spin-orbit interaction, the electron g*-factor decreases and by increasing the temperature, the electron g*-factor increases.
