摘要: Carbon nanotube (CNT) arrays are being considered as thermal interface materials (TIMs). Using a phase sensitive transient thermo-reflectance technique, we measure the thermal conductance of the two interfaces on each side of a vertically aligned CNT array as well as the CNT array itself. We show that the physically bonded interface by van der Waals adhesion has a conductance $\sim $10$^{5} $ W/m $^{2} $ K and is the dominant resistance. We also demonstrate that by bonding the free-end CNT tips to a target surface …
