Abstract
The influence of phonon focusing on phonon transport in semiconductor and dielectric crystals with different types of elastic-energy anisotropy at low temperatures is investigated. McCurdy’s effects in the thermal conductivity of elastically anisotropic crystals in the mode of Knudsen phonon gas flow are calculated. The influence of phonon focusing on the propagation and boundary scattering of phonons in samples with square and rectangular cross sections is analyzed, and a physical explanation of McCurdy’s effects is given.
