Abstract

An analysis of the temperature-dependent Hall resistivity together with the longitudinal conductivity of a metallic 2D hole system within the ballistic regime was performed. The low magnetic field Hall coefficient was found to be enhanced when temperature decreases. Coulomb interaction corrections of a Fermi liquid (FL) in the ballistic regime can not explain the enhancement of the Hall resistivity. The results show that the enhanced slope of the Hall resistivity is qualitatively and quantitatively inconsistent with interaction corrections to FL.
