Uncovering operational mechanisms of a single-walled carbon nanotube network device using local probe electrical characterizations.

The apparent field-effect-transistor (FET)-like operations of a device based on a network of single-walled carbon nanotubes (SWCNTs) are elucidated with the help of local probe electrical characterization methods using an atomic force microscope. The apparent switching behavior of the device with an on-off ratio>10(4) is found to be due to just two… CONTINUE READING
