31. Phonon detection is accomplished with superconduction FET amplifier.32. Phonon -polaritons propagate laterally away from the excitation region and into the waveguides.33. The first frame shows the initial phonon -polaritons at the time of generation. 34. The quantum of lattice vibration is called phonon . 35. This I had equivalenced with photon / phonon . 36. Therefore, the phonon thermal conductivity displays a peak and decreases with increasing temperature. 37. The electron-phonon coupling is responsible for electron generation in the pV cell. 38. The two most important anharmonic effects are the thermal expansion and the phonon thermal conductivity. 39. Time variation due to phonon decay is described with a relaxation time ( ? ) approximation 40. The screened potential determines the inter atomic force and the phonon dispersion relation in metals.
