Коэффициенты усиления потока фононов в кристаллах с различным типом анизотропии упругой энергии

AbstractPhonon pulse propagation in cubic crystals with different elastic energy anisotropy types is considered. A closed analytical expression is derived for the phonon flux enhancement factor. The features of its dependences on the isoenergetic surface curvature types are analyzed for all acoustic... View More
