Kapitza Resistance between Few-Layer Graphene and Water
· The Kapitza resistance (RK) between few-layer graphene (FLG) and water was studied using molecular dynamics simulations. The RK was found to depend on the number of the layers in the FLG though surprisingly not on the water block thickness. This distinct size dependence is attributed to the large difference in the phonon mean free path between the FLG and water.

Kapitza resistance at the liquid—solid interface
Using equilibrium and non-equilibrium molecular dynamics simulations we determine the Kapitza resistance (or thermal contact resistance) at a model liquid-solid interface. The Kapitza resistance (or the associated Kapitza length) can reach appreciable values when the liquid does not wet the solid. The analogy with the hydrodynamic slip length is discussed.
