| الوصف: | Reflectivity of the plasmon–phonon modes in grating‐coupled AlGaN/GaN heterostructures grown either on GaN or on SiC substrates were studied across the Reststrahlen band of semiconductors. The reflection spectra are experimentally obtained and fitted with the numerical data modeled using a rigorous coupled wave analysis method. Analysis of the field plots revealed that the origin of the intense multipeak reflectance minima can be attributed to the strong phonon interaction with the grating plasmons, demonstrating new possibilities for the localization of phonon‐polariton modes within AlGaN/GaN layers. The results are important for the optical and electrical engineering of new sensors, emitters, and modulators employing wide bandgap semiconductor junctions coupled with the metal gratings of the specified design. |
