Molecular dynamics simulation of the thermal transport on holey copper substrates


The mechanism behind heat transfer at the nanoscale is different from that at macroscale as the size of the surface structure reaches the phonon mean free path. In this work, we investigate the effect of the presence of a nano hole on the solidliquid heat transfer. To this end, we perform molecular dynamics simulations of a water film in contact with a copper substrate with nanoscale surface structures–here represented by nanoholes. Our results indicate that the presence of a nanohole with diameter of 20 Å increases significantly the transfer of thermal energy from the copper substrate to the water film.
