摘要：
Herein, the results of theoretical investigation of anisotropic thermal conductivity of AlGaN/GaN superlattices (SLs) are presented. For calculations, the Boltzmann transport equation in the relaxation time approximation is used. Results of computations are compared with experiment and theoretical result obtained using Callaway model. Good agreement between experimental and theoretical results is observed. Opportunity of use of the Callaway model for calculation of anisotropic thermal conductivity of SLs is discussed.
