“…In the case of mixed disorder (figures 1(a) and (b)) we notice that the PD is doubly peaked near π/2 and 3π/2 in the absence of nonlinearity, while in disordered barriers and wells, only a single peak appears near 3π/2 and π/2, respectively. Therefore the results obtained previously in this regime [4,9,10] cannot be extended to an arbitrary type of disorder and the superposition effect of these two types of disorder observed in the case of mixed disorder for the transmission properties [12] is also observed in the PD behaviour. In the presence of attractive (repulsive) NL potential, the peak at 3π/2 (π/2) disappears in the mixed disorder case, while the other peak is shifted towards π.…”
