| 摘 要： | The interface phonon-polaritons in quantum well systems consisting of polar ternary mixed crystals are investi-gated. The numerical results of the interface phonon-polariton frequencies in the GaAs/AlxGa1-xAs, ZnSxSe1-x/ZnS, and ZnxCd1-xSe/ ZnSe quantum well systems are obtained and discussed. It is shown that there are six branches of interface phonon-polariton modes distributed in three bulk phonon-polariton forbidden bands in the systems. The electric fields of interface phonon-polaritons are also presented and show the interface locality of the modes. The effects of the ’two-mode’ and ’one-mode’ behaviours of the ternary mixed crystals on the interface phonon-polariton modes are shown in the dispersion curves.

| Abstract: | The interface phonon--polaritons in quantum well systems consisting of polar ternary mixed crystals are investigated. The numerical results of the interface phonon--polariton frequencies in the GaAs/AlxGa1 - xAs, ZnSxSe1 - x/ZnS, and ZnxCd1 - xSe/ ZnSe quantum well systems are obtained and discussed. It is shown that there are six branches of interface phonon--polariton modes distributed in three bulk phonon--polariton forbidden bands in the systems. The electric fields of interface phonon--polaritons are also presented and show the interface locality of the modes. The effects of the 'two-mode' and 'one-mode' behaviours of the ternary mixed crystals on the interface phonon--polariton modes are shown in the dispersion curves. |
