Combined measurements of the photoelectromagnetic effect and photoconductivity in three different geometries can be used to determine the anisotropy factors (μn∥/μn⊥, μp∥/μp∥) and the mobility ratios (μn∥/μp∥, μn⊥/μp⊥) in anisotropic semiconductors. In the present work this method has been applied to mercuric iodide; previous data on electron mobilities are confirmed, whereas the hole mobility is nearly isotropic.
