摘要：
A simple model for an electron moving in a disordered one-dimensional system is investigated analytically and the persistent current in this model of a disordered mesoscopic system is studied. We show that persistent currents decrease exponentially with increasing sample circumference. Our analysis is based on comparison with an exact calculation of the average resistance of a disordered one-dimensional chain.
