Field-Structured Chemiresistors
We have developed a significantly improved chemiresistor for sensing volatile organic compounds that consists of Au-coated Ni particles organized into electrically conducting pathways in a polymer matrix by a magnetic field [1]. This sensor overcomes the problems inherent to conventional carbon-black chemiresistors, while achieving an unprecedented magnitude of response. When exposed to chemica...
متن کاملPolycrystalline graphene ribbons as chemiresistors.
A IO N Graphene is a two-dimensional semimetal with zero band gap that exhibits excellent electrical, mechanical and thermal properties.[1,2] Transport through delocalized pi bonds allows charge carriers in graphene to achieve high mobility[3,4] for both electrons and holes, over ∼105 cm2/V·s for freely suspended graphene and >104 cm2/V·s for graphene on SiO2. Recent studies have suggested that...
متن کاملMolecular adsorption to LiMo3Se3 nanowire film chemiresistors.
Thin films of metallic nanowire bundles derived from the Chevrel compound LiMo3Se3 undergo reversible increases of their electrical resistance (up to 70%) upon exposure to vapors of organic solvents (Qi, X. B.; Osterloh, F. E. J. Am. Chem. Soc. 2005, 127 (21), 7666-7667). Using quartz crystal microbalance measurements with four analytes, we demonstrate here that the temporal and steady-state re...
