“…For instances, ATR was applied to study the SPP characteristics of GaN, indium nitride and aluminium nitride semiconductors. SPP is a hybrid mode resulted from the coupling of transverse magnetic (TM) photon and optical phonon localized near the surface of the polar crystal [10,11]. Understanding of the material supported SPP mode is useful because the manipulation of the SPP mode has been shown to provide applications in developing several modern devices such as resonant-based sensor and thermo-photovoltaic system.…”

In this work, room temperature polarized infrared attenuated total reflection (ATR) spectroscopy was employed to characterize a nanoporous GaN thin film with honeycomb structure. Prominent ATR dips due to the surface phonon polariton (SPP) and guided waves of nanoporous GaN thin film were observed. Both SPP resonance and guided waves were detected in the p-polarized ATR spectrum while only guided waves were detected in the s-polarized ATR spectrum. The ATR results were compared with the theoretical spectra generated by means of effective medium model. Good agreement was achieved between the measured and theoretical spectra. Finally, the thickness and porosity of porous layer were determined unambiguously.
