Oscillatory and nonlinear effects in bismuth

"High-temperature" quantum oscillations

● The new type quantum oscillations of kinetic coefficients (magnetoresistance and thermoelectromotive) – quantum "high-temperature" oscillatory kinetic effect is found [1, 2] and experimentally investigated in bismuth. It was shown that HTO arise from the intervalley electron-hole scattering as a result of interference between carrier density oscillations at the Fermi level of the electron and hole parts of the energy spectrum [3-5].

Effects of phonon generation in bismuth

· Transport phenomena that arise from relaxation processes in the electron and phonon systems under the supersonic electron drift in the magnetic field (the Esaki effect) are investigated in bismuth [1, 2].
