Determining effective mass from temperature dependence of SdH oscillations.
(a) Δρxx as a function of 1/B at different temperatures obtained by subtracting a smooth background. LLs N = 2, 3 are labeled by the arrows. (b) SdH oscillation amplitude as a function of temperature at different magnetic fields. The solid lines represent the best fits using equation (1). Data points obtained at low fields can be found in the Supplementary Figure S5. (c) Extracted effective mass at different magnetic fields. The line is a quadratic magnetic field dependent fit.
