Abstract

Heat-conduction interfaces that employ carbon nanotube (CNT) arrays have been fabricated and studied experiementally using a reference calorimeter testing rig in a vacuum environment with infrared temperature measurements. Arrays of multiwalled CNTs are grown directly on silicon substrates with microwave plasma-enhanced chemical vapor deposition. Iron and nickel were used as CNT catalysts. CNT arrays grown under differnt synthesis conditions exhibit different pressure-contact conductance characteristics. The thermal contact resistance of CNTs with a copper interface exhibits promising results with a minimum value of 19.8 mm^2K/W at a pressure of 0.445 MPa.
