Comment on ‘‘Analysis for determining thermal diffusivity from thermal pulse experiments’’

Abstract

An error has been noted in the seminal work by Cape and Lehman [J. Appl. Phys. 34, 926 (1963)] for determining thermal diffusivity values from the results of pulse heating experiments. In the present communication, the correct formula has been determined and some estimates have been made of the errors resulting from application of the incorrect formulation.
