  A clear understanding and proper control of interfacial thermal transport is
important in nanoscale device. In this review, we first discuss the theoretical
methods to handle the interfacial thermal transport problem, such as the
macroscopic model, molecular dynamics, lattice dynamics and modern quantum
transport theories. Then we discuss various effects that can significantly
affect the interfacial thermal transport, such as the formation of chemical
bonds at interface, defects and interface roughness, strain and substrates,
atomic species and mass ratios, structural orientations. Then importantly, we
analyze the role of inelastic scatterings at the interface, and discuss its
application in thermal rectifications. Finally, the challenges and promising
directions are discussed.
