Specific heat of 2D electrons in GaAs/GaAlAs multilayers.
01 January 1985
We report the first observation of the magnetic field dependent electronic specific heat in GaAs/GaAs multilayers. With a heat pulse technique oscillations of the sample temperature in the order of mK were observed. Both, intra-and inter Landau level contributions could be distinguished. Theoretical fits to the data reveal a density of states consisting of Gaussian peaks on a flat background.
