Modeling a Suspended Nanotube Oscillator

Suspended single-walled carbon nanotube fluidic sensors.

In this paper, we demonstrate the fabrication of liquid flow sensors employing partially suspended single-walled carbon nanotubes (SWNTs). We have found that the sign of the conductance change in SWNT flow sensors is not influenced by the direction of water flow for both supported and suspended devices. Therefore, the streaming potential is not the principal mechanism of the SWNT sensor respons...

Optoelectronic Probes of Suspended Carbon Nanotube Transistors

Suspended carbon nanotube transistors are used as nanoscale optoelectronic probes to investigate the electrical and optical processes in biological systems due to their high sensitivity, robust electrochemical stability, and high surface to volume ratio. Taking advantage of dual-optical trapping technique and scanning photocurrent microscopy, we are able to study the interface between carbon na...

Carbon nanotube field effect transistors with suspended graphene gates.

Novel field effect transistors with suspended graphene gates are demonstrated. By incorporating mechanical motion of the gate electrode, it is possible to improve the switching characteristics compared to a static gate, as shown by a combination of experimental measurements and numerical simulations. The mechanical motion of the graphene gate is confirmed by using atomic force microscopy to dir...
