Molecular Dynamics Studies of Thermal Boundary Resistance in Carbon-Metal Interfaces
Molecular dynamics is used to study the interfacial thermal conductance between graphitic structures and metals. It is shown that with different metals, the conductance can vary by ∼4-fold, allowing the control of thermal transport in nanocomposites and nanoelectronic devices. The experimental values of conductance are higher by 10–20 MW m−2 K−1 compared to simulations. We suggest that in addition to lattice vibrations, an electromagnetic coupling between Johnson–Nyquist electric currents in the metal and graphite may contribute to the interfacial thermal conductance.
