Annotation
The study of charge transfer in rare earth chalcogenide semiconductor TmTe has been carried out by using experimental and theoretical X-ray powder diffraction (XRPD) data. The direction and amount of charge transfer are inferred by plotting and comparing the structure factor of the components. Thus, a charge transfer of 0.15 electrons is obtained in TmTe from Tm to Te.
