摘要
Nanocable devices (see Figure) of individual single-walled carbon nanotube/ polypyrrole (PPy) and their synthesis, transport studies, and chemical -sensing applications are investigated. They exhibit suppressed conductance, in contrast to the anticipated combined conductance from the nanotubes and PPy. Further deposition of PPy leads to a recovery in conductance. These devices are demonstrated to work as chemical sensors.
