Abstract

The diffusion of electrons in two dimensions is investigated when the model space has one or more sinks. A random walk approach is used to follow each electron until it is trapped at a sink. The times to capture are combined to form the survival time distribution. This is found to decay exponentially with time for the cases considered here. The characteristic time for the decay depends directly on the model space area and inversely on the number of traps or sinks and the trap radius. Power laws with non-integers are found for all three parameter dependences.
