  The thermal transport across inorganic/organic interfaces attracts interest
for both academic and industry due to its widely applications in flexible
electronics etc. Here, the interfacial thermal conductance of inorganic/organic
interfaces consisting of silicon and polyvinylidene fluoride is systematically
investigated by molecular dynamics simulations. Interestingly, it is
demonstrated that a modified silicon surface with hydroxyl groups can
drastically enhance the conductance by 698%. These results are elucidated based
on interfacial couplings and lattice dynamics insights. This study not only
provides feasible strategies to effectively modulate the interfacial thermal
conductance of inorganic/organic interfaces but also deepens the understanding
of the fundamental physics underlying phonon transport across interfaces.
