Weak localization in macroscopically inhomogeneous two-dimensional systems: a simulation approach
arXiv:cond-mat/0104319 · doi:10.1103/PhysRevB.64.165404
Abstract
A weak-localization effect has been studied in macroscopically inhomogeneous 2D system. It is shown, that although the real phase breaking length tends to infinity when the temperature tends to zero, such a system can reveal a saturated behavior of the temperature dependence of that parameter, which is obtained from the standard analysis of the negative magnetoresistance and usually identified by experimentalists with the phase braking length.
