  • Calculation of the Hall Coefficient in Doped Semiconductor Superlattices with a Perpendicular Magnetic Field under the Influence of a Laser Radiation

    • Authors: Bui, Dinh Hoi; Pham, Thi Trang; Nguyen, Quang Bau (2013)

  • We consider a model of the Hall effect when a doped semiconductor superlattice (DSSL) with a periodical superlattice potential in the z-direction is subjected to a crossed dc electric field (EF) and magnetic field , in the presence of a laser radiation characterized by electric field (where and are the amplitude and the frequency of the laser radiation, respectively). By using the quantum kinetic equation for electrons and considering the electron - optical phonon interaction, we obtain analytical expressions for the Hall conductivity as well as the Hall coefficient (HC) with a dependence on B, , , , the temperature T of the system and the characteristic parameters of DSSL. The an...

  • Investigation of Magneto-phonon Resonance in Graphene Monolayers

    • Authors: Le, Thi Thu Phuong; Tran, Thi My Duyen; Vo, Thanh Lam; Bui, Dinh Hoi (2017)

  • In this work, utilising the linear response theory we calculate the magneto conductivity (MC) in graphene monolayers, subjected to a static perpendicular magnetic field. The interaction of Dirac fermions with optical phonon via deformation potential is taken into account at high temperature. The dependence of the MC on the magnetic field shows resonant peaks that describe transitions of electrons between Landau levels via the resonant scattering with optical phonons. The effect of temperature on the MC is also obtained and discussed.
