| Research Abstract |
In this study, molecular dynamics (MD) simulations of the interface between self-assembled monolayers (SAMs) on the metal surface and solvents were performed in order to investigate heat transfer characteristics at the interface. By using nonequilibrium MD (NEMD) techniques, in which a temperature gradient across the interface was imposed, the contributing factors to interfacial thermal transport properties over the substrate-SAM-solvent interface were evaluated. As a result, it was found that thermal boundary resistance at the SAM-water interface is strongly influenced by the terminal groups of SAM. The effect of adsorption structure of SAM on thermal boundary resistance was also elucidated.
