The direct band-to-band transition energies Edg at various temperatures were determined accurately through line shape fit of the experimental PzR spectra. The temperature dependence of Edg is analyzed by the Varshni equation [Y. P. Varshni, Physica, (Amsterdam) 34, 149 (1967)] and an expression containing the Bose-Einstein occupation factor for phonons proposed by L. Viña, S. Logothetidis, and M. Cardona [Phys. Rev. B 30, 1979 (1984)]. The parameters that describe the temperature dependence of Edg are evaluated and discussed. © 2000 American Institute of Physics. |
