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