Abstract

I describe a set of computational experiments using molecular dynamics simulations, showing that the interface between two solid materials can be described as an autonomous thermodynamical system. By making use of the Gibbs description for such an interface, I discuss a robust nonequilibrium thermodynamics theoretical framework providing information about its corresponding thermal boundary resistance. In particular, I show that the termal resistance of a junction between two pure solid materials can be regarded as an interface property, depending solely on the interface temperature.
