Abstract

We report signatures of quantum magneto transport steps in a Bi2Se3 single crystal. The Bi2Se3 crystal is grown by self-flux method through solid-state reaction. Details of its structural analysis along with physical properties in terms of low temperature and high field transport, thermal (heat capacity), Raman, X-ray photo electron and angle resolved photo electron spectroscopy were reported earlier (J. Sup. Novel. Mag. 30, 2031 2017). In a present short letter, we show the details of its 2 K and up to 14 Tesla magneto transport, exhibiting quantum transport (QT) like steps above say 11 Tesla field. The possible QT steps cannot be modelled with the SdH (Shubnikov-de Haas) or other possible quantum oscillations. The observed QT like steps are possibly the result of the mixed out-of-plane Rxy(H) and in-plane Rxx(H) contributions from the misaligned [00l] planes of the studied crystal and this may happen with other studied topological insulator (TI) crystals as well. Our careful assessment of crystal XRD data shows the same.
