Abstract: Abstract: We report the anisotropic optical property study on the band-edge excitonic transitions of ReSe2 single crystals doped with Au. The temperature-dependent piezoreflectance (PzR) and photoreflectance (PR) spectra with E||b and E⊥b polarizations in the near band-edge region provide conclusive evidence that band-edge excitonic transition features, namely , and are from different origins. The features located at higher energy side correspond to the Rydberg series starting with principal quantum number n = 2. The doping effects were presented and discussed.
