ABSTRACT
We report on cyclotron effective mass measurement in indium nitride epilayers grown on c-sapphire, using the thermal damping of Shubnikov-de-Haas oscillations obtained in the temperature range 2–70 K and under magnetic field up to 60 T. We unravel an isotropic electron cyclotron effective mass equal to 0.062±0.002m0 for samples having electron concentration near 1018 cm-3. After nonparabolicity and polaron corrections we estimate a bare mass at the bottom of the band equal to 0.055±0.002m0.

    Electron transport is a key process in the physics of Hall thruster discharges. Therefore, a kinetic description of the heavy particles (Xe) as well as electrons is required. The ideal numerical model would be a particle model for all the species. Nowadays, such a model is unpractical because it...

    The effect of a high magnetic field on the electronic structure of HTSC cuprates is considered. The study is performed in the t- t′- t″- J* model, and the high magnetic field effect is taken into account not only as the Zeeman splitting of the one-electron levels, but also in the...

    We report quantum interferences in a multi-channel Luttinger liquid coupled by a microwave field at two pinning sites where electrons experience forward scattering. We use a magnetic field to tune the phase difference between charge density waves propagating in each channel. The interferences...

    The transport property of a lateral two-dimensional paramagnetic diluted magnetic semiconductor electron gas under a spatially periodic magnetic field is investigated theoretically. We find that the electron Fermi velocity along the modulation direction is highly spin dependent even if the spin...
