We report on the extensive structural and optical studies of Re-doped molybdenum disulfide (MoS2) grown by the chemical vapor transport (CVT) method using Br-2 as a transport agent. To evaluate the influence of Re on the structural properties of crystals, we have conducted X-ray diffraction (XRD) and transmission electron microscopy (TEM) experiments. For optical characterization, we carried out piezoreflectance (PzR) and electrolyte electroreflectance (EER) measurements. The Re dopant clearly caused a structural change in MoS2 from a two-layer hexagonal (2H) structure to a three-layer rhombohedral (3R) structure, which has been clearly verified and identified herein.
