Abstract: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 di… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
