Abstract: There are provided a fabricating method of a carbon nanotube-based field effect transistor having an improved binding force with a substrate and a carbon nanotube-based field effect transistor fabricated by the fabricating method. The method includes forming an oxide film on a substrate, forming a photoresist pattern on the oxide film, forming a metal film on the entire surface of the oxide film having the photoresist pattern, removing the photoresist by lifting off, adsorbing carbon nanotubes on the substrate from which the photoresist is removed, performing an annealing process to the substrate to which the carbon nanotubes are adsorbed, and removing the metal film. Since an adhesive strength between a substrate and carbon nanotubes increases, stability and reliability of a field effect transistor can be improved. If the field effect transistor is applied to a liquid sensor or the like, a lifespan of the sensor can be extended and reliability of a measurement result obtained by the sensor can be improved.

Abstract: A gas sensor and a method of fabricating the same are provided. The gas sensor includes a substrate, carbon nanotubes (CNTs) adsorbed onto the substrate, platinum nanoparticles (NPs) decorated to surfaces of the CNTs, and an electrode formed on the substrate onto which the CNTs with the platinum NPs decorated thereto are adsorbed. When the platinum NPs and CNTs are used as a sensing material, the gas sensor can be useful in sensing gases with high sensitivity even when present at a low concentration of at least 2 ppm and stably sensing noxious gases such as C6H6, C7H8, C3H6O, CO, NO, and NH3 as well as NO2, and can have particularly excellent selectivity and response characteristics with respect to NO2 gas.
