Abstract:A novel approach for cross-plane thermal conductivity and diffusivity measurement in thin-films by combining steady state comparative-longitudinal heat flow method (SCHF) and the Angström method is reported. A thin specimen was sandwiched between two identical metal cylinders; thermal wave was introduced from the lower cylinder and crossed through the specimen then passed to the upper cylinder where steady heat flux is enforced. There were four equally spaced thermocouples on both upper and lower cylinders to … Show more
