Nous avons fait des expériences de réflexion des phonons par des surfaces libres de Si [100] dans lesquelles on pouvait distinguer phonons réfléchis et phonons diffusés, les réfléchis se propageant selon . La proportion phonons diffusés sur phonons spéculairement réfléchis est une fonction croissante de la fréquence.In reflection experiments at free silicon [100]- surfaces we could distinguish between specularly and diffusely reflected transverse phonons propagated along - directions. With increasing phonon frequency the number of diffusely scattered phonons increase relative to that of specularly reflected phonons
