摘要

We have carried out a systematic evaluation of the accuracy of the charge density Values obtained by fitting a modified hydrodynamical model to Raman spectra. The hydrodynamical model has been extended to provide a more accurate evaluation of wave vector dependence, conduction band nonparabolicity and free carrier thermal distribution effects through an energy dependent effective mass, so that it can be applied to a wide range of carrier densities. We have used this extended model to fit the coupled-mode Raman spectra obtained from a series of n-InP samples with electron densities in the 10(17)-10(19) cm(-3) range, and the carrier density values obtained follow closely the results of the more elaborate Lindhard-Mermin model over the whole density range.
