| Abstract: | This paper discusses the question of how isotopic disorder affects the position of the thermal-conductivity maximum of germanium.
The discussion is in terms of a Callaway-type model. Experimental data on the thermal conductivity of a natural Ge crystal
and of highly enriched Ge70 crystals are analyzed.
