Abstract

We present a theoretical and experimental study on the low-temperature electron mobilities due to ionized impurity scattering in a multisubband quasi-two-dimensional semiconductor system. The scattering rate is obtained from the solution the Lippmann-Schwinger equation in momentum space and the screening is considered within the random-phase approximation. A quantitative agreement is reached between the theoretical and experimental results for both the quantum and transport mobilities
