    Different sensing mechanisms in single wire and mat carbon nanotubes chemical sensors

    Chemical sensing properties of single wire and mat form sensor structures fabricated from the same carbon nanotubes (CNT) materials have been compared. Sensing properties of CNT sensors were evaluated upon ele...

    Ion irradiation effects on conduction in single-wall carbon nanotube networks

    We have measured how irradiation by Ar+ and N+ ions modifies electronic conduction in single-wall carbon nanotube (SWNT) networks, finding dramatically different effects for different thicknesses. For very thin t...
