FIG. 1.

Calculated FIR transmission spectra in an oblique incidence for free standing thin films of -GaN of various thicknesses ranging from 0.5 to . The full lines (—) represent the results of -polarization while the dotted lines (----) represent the calculations in the -polarization.

FIG. 2.

Calculated FIR transmission spectra in an oblique incidence for a thin film of -GaN/AlN (buffer)/GaAs. The full lines (—) represent the results of -polarization while the dotted lines (----) represent the calculations in the -polarization.

Image of FIG. 3.
FIG. 3.

Calculated LO phonon-plasmon coupled modes and in -GaN as a function of the free carrier concentration along with the experimental data from Refs. 15 and 16. The , , and are also displayed.

Image of FIG. 4.
FIG. 4.

Calculated FIR transmission spectra in an oblique incidence for a thin -GaN film of different charge carrier concentrations in the -polarization. Our calculated shifts in modes in GaN for , , and (see text) are found to be in excellent agreement with the experimental Raman (see Ref. 16) scattering data.
