Abstract	:	Several groups have previously measured the thermal properties of millimeter sized Carbon Nanotubes mats. Although these studies can help us to understand the thermal properties of these materials, it is difficult to extract the intrinsic thermal properties of a single nanotube from these 'bulk' measurements. Thus we needed a mesoscopic device which hybrids nanotubes to microelectro-mechanical systems (MEMS) to use them for thermal property measurements (TEP) of Single Wall Carbon Nanotubes. This project involved sensing thermal measurements through thermocouples and using unique fabrication design for obtaining thermally isolated source and drain. Heating a Nichrome metal structure submerged under a source pad and heated by a voltage generator created the seebeck effect. The thermopower "S" values were measured at different temperatures. The measured temperature gradient was well in accordance to the MEMCAD analysis. This proved the feasibility of using it as a chemical sensor. Its adsorption with other gases was studied.
