Temperature dependence of heat-pulse propagation in sapphire

View publication

Abstract

Results of heat-pulse measurements between 4 and 54°K are reported for sapphire and show that the propagation is ballistic below 18°K and diffusive above 40°K. In the intermediate range, the propagation is a superposition of the two. © 1966 The American Physical Society.
