Thermal transport at nanostructured solid-liquid interface is becoming ever more important with the development of next-generation high efficiency thermoelectric devices. Kapitza resistance has considerable effects on heat transfer in micro/nanochannel. However, direct experimental measurements of heat flow across the nanostructured solid-liquid interface in nanoscale systems are still challenging. In this case, molecular dynamics (MD) simulations are feasible to investigate the solid-liquid interface characteristics.
