Quantum and classical scattering times due to charged dislocations in an impure electron gas

Quantum and classical scattering times due to charged dislocations in an impure electron gas

We derive the ratio of transport and single-particle relaxation times in three- and two-dimensional electron gases due to scattering from charged dislocations in semiconductors. The results are compared to the respective relaxation times due to randomly placed charged impurities. We find that the ratio is larger than the case of …
