Abstract
Witek [Diamond Relat. Mater. 7 (1998) 962] has shown that the measured ther mal conductivities of the adamantine nitrides AlN, GaN and cubic BN are wel l below the values calculated from a simple expression he derived for the i deal crystals. He ascribed these discrepancies to lattice defects in the ca ses of AlN and GaN, but to isotopes for BN. It is shown here, using a modic um of theory that these explanations are almost certainly correct. (C) 1999 Elsevier Science S.A. All rights reserved.
