摘要： A gas sensing device (nanosensor) includes a substrate with at least a pair of conductive electrodes spaced apart by a gap, and an electrochemically functionalized semiconductive nanomaterial bridging the gap between the electrodes to form a nanostructure network. The nanomaterial may be single-walled carbon nanotubes (SWNTs) functionalized by the deposition of nanoparticles selected from the group consisting of an elemental metal (e.g., gold or palladium), a doped polymer (e.g., camphor-sulfonic acid doped polyaniline), and a metal oxide (e.g. tin oxide). Depending on the nanoparticles employed in the functionalization, the nanosensor may be used to detect a selected gas, such as hydrogen. mercury vapor, hydrogen sulfide, nitrogen dioxide, methane, water vapor, and/or ammonia, in a gaseous environment.

摘要： A selective nanoscale asymmetric gas sensor is disclosed, the sensor including a first electrode having a Schottky-type contact to a nanoengineered transducer with a barrier height between energy levels of the first electrode and the nanoengineered transducer; and a second electrode having an Ohmic contact to the nanoengineered transducer with a smaller or no barrier height than the first electrode. The first electrode can be palladium and the second electrode can be gold.
