Abstract:
The reflection and attenuated total reflection spectra of aluminum and gallium nitride films doped with silicon on sapphire substrates with a buffer layer of aluminum nitride have been measured. In the spectra of attenuated total reflection, surface phonon and plasmon–phonon polaritons were observed. A high concentration of charge carriers in the gallium nitride film and their practical absence in the aluminum nitride film were experimentally observed.
Keywords:
aluminum and gallium nitrides, reflection and ATR spectroscopy, surface polaritons.
