INTERFACIAL 3-PHONON PROCESSES AND ANOMALOUS INTERFACIAL ENERGY-TRANSPORT Academic Article uri icon

abstract

  • Interfacial three-phonon processes require only a moderately strong matrix element ( 105 erg cm2) to explain the anomalous energy transport observed at high phonon frequencies across the interface between ordinary and "quantum" materials. This mechanism is qualitatively consitent with a wide variety of experiments, and has a large number of symmetry-allowed couplings with which to explain the details of particular experiments. Near "onset", this mechanism contributes anomalous reflection and transmission varying as the sixth power of the incident phonon frequency. 1979.
