Abstract

The interpretation of thermal conductivity measurements on

{YBa}_{2} ({Cu}_{1 - x} {Zn}_{x})_{3} O_{7 - δ}

by Houssa, Ausloos, and Cloots [Phys. Rev. B 56, 6226 (1997)] in terms of Zn substitution leading to electron doping and a concomitant shift in the Fermi level away from a van Hove singularity peak in the density of states is shown to be inconsistent with the wider body of experimental data.
