We have simultaneously determined the densities and mobilities of light and heavy holes at various temperatures (12K to 300K) in two molecular beam epitaxy-grown p-type Hg1-xCdxTe (x=0.224) samples from variable magnetic-field Hall measurement by using a hybrid approach consisting of mobility spectrum analysis followed by a multi-carrier fitting procedure.In addition, we directly observe the contribution of the light hole to the conductivity tensor component. The experimental values obtained in this work should be useful in modeling of HgCdTe infrared detectors.
