Abstract:

A weak-localization effect has been studied in macroscopically inhomogeneous two-dimensional system. It is shown that there is a regime where fits of the low-field negative magnetoresistance with the standard weak localization theory for a uniform system give a dephasing time which saturates as one goes to lower temperatures, even though the true dephasing time diverges as the temperature goes to zero.
