Ionized-impurity scattering of holes has been studied in isotopically engineered p-type Ge:Ga,As samples with compensation ratios between 0.08 and 0.61. Experimentally measured Hall mobilities at temperatures between 10 and 300 K are quantitatively compared with existing theories of ionized impurity scattering in highly compensated semiconductors. We find fair agreement with the theory based on the correlated distribution of ionized impurity centers.
