Following pulsed irradiation of disordered solids, optical absorption of trapped electrons decays in the far red and increases in the visible. The random-walk model of Scher and Control, quantitatively apphcable to electron mobility by timeof-flight, supports hopping to successively deeper traps. Ba
We study the survival probability of a particle that performs a random walk in a medium with traps where the trapping strength V is distributed randomly. We use an approach which is asymptotically exact and brings Wn(s), the number of distinct sites s visited after n steps, into play. Particularly i
