Abstract:Single crystals of W-doped ReSe2 have been grown by chemical vapor transport process with bromine as the transporting agent. Single crystalline platelets up to 3×3 mm surface area and 100 µm in thickness were obtained. From the X-ray diffraction patterns, the doped crystals are found to crystallize in the triclinic-layered structure. The electrical anisotropy has been investigated along and perpendicular to the b-axis on the van der Waals plane by temperature-dependent conductivity and Hall effect measurements. The influence of the dopant will be compared and discussed.
