WebShubnikov-de Haas (SdH) oscillations under a dc current bias are experimentally studied on a Hall bar sample of single-layer graphene. In dc resistance, the bias current shows the common damping effect on the SdH oscillations and the effect can be well accounted for by an elevated electron temperature that is found to be linearly dependent on the current bias. WebThe Shubnikov-de Haas (SdH) oscillations occur at the lower fields while the Quantum Hall (QH) oscillations occur at the higher. fields. Both SdH and QH oscillations have the same periods: εF /u0001ωc , where εF is the Fermi. energy and ωc the cyclotron frequency. Since the phases are different by π/2, transitions.
