MEASUREMENT TECHNIQUE OF THERMAL CONTACT RESISTANCE OF A CARBON NANOTUBE TIP
Carbon nanotube (CNT) has a very high intrinsic thermal conductivity and is expected to be used in a variety of thermal applications. However, our lack of understanding of the thermal contact resistance (TCR) between CNT and surrounding material should cause wrong thermal design. Some analytical and molecular dynamics studies have been reported on it but there is no reliable experimental method to quantitatively investigate the interface issues. This paper reports on a new technique for measuring the TCR between an individual CNT tip and a solid surface by using a platinum hot-film sensor. CNT is set on the film sensor as to protrude from an edge of sensor substrate and this CNT probe is manipulated as to contact with target surface. We introduce two kinds of method to obtain the ITR. A preliminary test was conducted by using a multi-walled CNT and both methods gave an identical thermal resistance of 1×106 K/W.
