Abstract

Abstract: Precise evaluation of the thermophysical properties of thin films is crucial for realizing high-performance flexible electrical and energy devices. The ultrafast laser-based time-domain thermoreflectance (TDTR) method is one of the most effective methods for examining the thermophysical properties of thin films attached to metals; however, conventional TDTR methods are mainly employed for an aluminum transducer layer, which is not used for conventional metal electrodes. Here, we developed a TDTR system designed for a gold transducer, which is a typical metal electrode in electronic devices, and evaluated the thermophysical properties of a carbon nanotube thin film adhered on a gold surface.
