For both planar and nanoparticle interfaces, polarizing the gold surface leads to an increase in G. Our explanation for this is the same as that of Bhattarai et al. The image charge and image dipole interactions present in the DR-EAM potential enhance the binding strength of all polar species, leading to enhanced coupling between the motion of solid and liquid phases, thereby enhancing thermal transport. For the planar interfaces, polarization of the gold surface does not appear to impact either solution-phase conductivity or interfacial thermal conductance. However, polarization of the spherical nanoparticles causes a significant increase in G (see table ).
