摘要：
New theoretical data are presented on the lattice thermal conductivity temperature dependence of cubic boron nitride single crystals. Their thermal conductivity increases with increasing isotope purity, with the maximum thermal conductivity occurring with either isotopically pure B-11 or B-10. The thermal conductivity is a symmetric function of isotopic composition with a minimum at 50% B-10. (C) 2000 Elsevier Science S.A. All rights reserved.
