| dc.description | Photoreflectance (PR) spectra have been measured to determine the fundamental-absorption-edge (E<sub>0</sub>) structure of hexagonal CdSe single crystal for both E c and E|| c polarizations at temperatures T between 77 and 300 K. The measured PR spectra are found to be successfully explained by an excitonic line shape for temperatures T below ~200 K and by a three-dimensional one-electron line shape for T>200 K. No clear evidence of the exciton interference effect has been observed within our experimental temperature range T = 77-300 K. The temperature dependence of the E<sub>0</sub>-exciton parameters (exciton energy, amplitude and broadening parameter) has been determined and analysed using the Varshni equation and an empirical expression of Bose-Einstein type. |
