Abstract
We present results from a quantum and semiclassical theoretical study of the rho(xy) and rho(xx) resistivities of a high mobility 2D electro n gas in the presence of a dilute random distribution of tubes with ma gnetic flux PHI and radius R, for arbitrary values of k(f)R and F = eP HI/h. We report on novel Aharonov-Bohm-type oscillations in rho(xy) an d rho(xx), related to degenerate quantum flux tube resonances, that sa tisfy the selection rule (k(f)R)2 = 4F(n + 1/2), with n an integer. We discuss possible experimental conditions where these oscillations may be observed.
