WebThe Shubnikov-de Haas oscillations are oscillations of the resistivity parallel to the current ow in the edge states of a 2DEG (2-dimensional electron gas) in an applied magnetic eld. Therefore they are related to the Quantum-Hall e ect. The Shubnikov-de Haas oscillations have a 1/B-periodicity. WebShubnikov-de Haas (SdH) oscillations, the most well-known magneto-oscillations caused by the quantization of electron energy levels in the presence of magnetic fields in two-dimensional (2D) electron systems, can be used to determine Fermi-surface properties and directly measure the Berry phase of the 2D systems. It is usually thought that transport …
