Theoretical investigation of the phonon-polariton mode in Czochralski-grown piezoelectric superlattice

• We propose the phonon-polariton mode of in Czochralski-grown piezoelectric superlattice.
• The mechanism for polariton coupling is analyzed.
• We discuss the factors that influence the properties of the phonon–polariton.
• Some potential applications are discussed.

The properties of phonon-polaritons in Czochralski-grown piezoelectric superlattice (CPSL), are studied theoretically. We propose the phonon-polariton mode of CPSL. The mechanism for polariton coupling is analyzed. We discuss the factors that influence the properties of the phonon-polariton. Some potential applications are also discussed.
