Thermal Transport across Solid Interfaces with Nanoscale Imperfections: Effects of Roughness, Disorder, Dislocations, and Bonding on Thermal Boundary Conductance

Figure 1

Schematic of a perfect and an atomically imperfect interface. A perfect interface is an atomically abrupt, coherent interface between two solids in intimate contact. The atomically imperfect interface depicted here occurs when the interface is not well defined due to atomic disorder (both structural and compositional), resulting in roughness and impurities around the interface.
