Low thermal contact resistance boron nitride nanosheets composites enabled by interfacial arc-like phonon bridge

Nature Communications
Two-dimensional materials with ultrahigh in-plane thermal conductivity are ideal for heat spreader applications but cause significant thermal contact resistance in complex interfaces, limiting their use as thermal interface materials.
