van der Waals (vdW) interface is a critical component in the performance of flexible devices, such as electronics, thermal, and thermoelectric devices. Recent advances in interface design using two-dimensional (2D) materials have allowed for studying various controlled interface properties. From the view of thermal management for 2D electronics, the study on heat transfer through vdW interfaces of layered 2D materials is of great importance because of their high heat generation and interfacial thermal mismatches. Understanding the heat and electrical transport correlation is essential for optimizing the performance of flexible devices and 2D electronics. However, the correlation between the heat and electrical transport characteristics across 2D vdW interfaces has yet to be elucidated in detail due to experimental limitations. To understand the correlation, we have employed time-domain thermoreflectance measurements using Au as a metal transducer (Au-TDTR) , and have investigated the correlation between heat and electrical transports across various vdW nano-interfaces. In this talk, I would like to discuss our resent results on the correlation between heat and electrical tranport across homo or hetero-interfaces, stacking angle controlled interfaces, and intercalated interfaces.
