Crossover from weak localization to weak antilocalization in a disordered microbridge

Year: 2003

Type: article

Abstract: We calculate the weak localization correction in the double crossover to broken time-reversal and spin-rotational symmetry for a disordered microbridge or a short disordered wire using a scattering-matrix approach. Whereas the correction has universal limiting values in the three basic symmetry classes, the functional form of the magnetoconductance is affected by eventual nonhomogeneities in the microbridge.
