| Outline of Final Research Achievements |
In order to develop technology to reduce thermal resistance over a liquid-solid interface and to predict variation of interfacial thermal resistance by structures at nanometer-precision, influences of structures at nanometer-precision on interfacial thermal resistance and thermal energy transport mechanisms at a liquid-solid interface are investigated directly by non-equilibrium classical molecular dynamics simulations. The thermal energy transport mechanism at a liquid-solid interface varies depending on the structure geometry at the nanometer scale and the liquid-solid interaction intensity, which causes changes in the interfacial thermal resistances that are quantitatively evaluated in the present study.
