The Shubnikov-de Haas(Sd H)oscillation,as evidenced by the oscillating resistivity as a function of magnetic field at sufficiently low temperature,is not uncommon in metals,semimetals and narrow gap semiconductors at their conducting state.The origin of Sd H oscillation is associated with Landau quantization,at which the cyclotron orbits of electrons are quantized.In other words,electrons can only occupy discrete energy levels,which are called the Landau levels.As the magnetic field increases,the split,quantized Landau levels move across the Fermi level and hence the material’s transport properties start to oscillate periodically.
