Transport properties of bismuth in quantizing magnetic fields

Abstract

After the early work of Steele and Babiskin, low-temperature transport properties in bismuth at high magnetic fields have been used to investigate the band structure, and only the periods in the quantum oscillations were of interest. In this paper, both the amplitude of the oscillations and the magnitude of the monotonic transport components (magnetoresistance, Hall, magneto-Seebeck, and Nernst) are investigated in the liquid-helium range, where phonon drag dominates the zero-field transport properties. Measurements are extended to the quantum regime where only a few of the electron levels are occupied. Experimental results on four transport components in the low-temperature range ($T<7$ K) and with transverse magnetic inductions up to $B=5T$ are reported. The amplitudes of the oscillations in the magneto-Seebeck component are in good qualitative agreement with those predicted by a recent quantum transport theory.
