Abstract: Abstract: Au-doped rhenium disulfide (Au-ReS2) layer crystals were grown by chemical vapour method with iodine as the transporting agent. The thin samples were investigated by polarization-dependent transmittance (T) and photoreflectance (PR) at 20 K with the optical polarization along and perpendicular to the crystal b-axis. The Au-ReS2 showed band gap anisotropy with respect to the b-axis. By comparing with the undoped sample, the indirect band gap deduced from the polarization-dependent T spectra shows a more pronounced red shift than the band edge excitonic transitions determined from polarization-dependent PR spectra.
