Landau Interaction Function for Electrons in the Surface Inversion Layer of a Semiconductor: A Test of Many-Body Theory

Abstract
The effective mass of a quasiparticle at the Fermi surface is given by m*=m(1+A1), where A1 is a Fourier coefficient of the Landau Fermi-liquid interaction function. Three different methods of evaluating the Landau interaction function are investigated and compared with experiment.
