Nanotube radio

We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. A copy of our Nano Letters manuscript may be found here.  Supplementary images and movies are available here.

   Extreme Thermal Test Platform

We have developed a thermal test platform capable of determining the electrical and thermal conductivity, as well as the thermal stability, of individual nanoscale objects to over 4,000K. The platform also yields simultaneous real-time atomic resolution imaging of the object as it evolves in time and temperature. A copy of the Physical Review Letter describing the platform and its application to carbon nanotubes and gold nanocrystals can be found here.  Supplementary images and movies are available here.

Nanoelectromechanical relaxation oscillator

We have developed a nanoelectromechanical relaxation oscillator with a surface-tension-driven power stroke.  The oscillator consists of two liquid metal droplets exchanging mass, and its frequency is directly controlled with a low-level dc electrical voltage.  A copy of the Applied Physics Letter can be found here.  Supplementary images and movies are available here.

   Nanoscale mass conveyor

We have developed a technique to move individual atoms back and forth along a carbon nanotube.  A copy of the Letter to Nature can be found here.  Supplementary images and movies are available here.

  Synthetic Rotational Nanomotor

Our group has been able to create the world's smallest synthetic motor using a multiwall carbon nanotube.  A copy of the Letter to Nature can be found here.  Supplementary images and movies are available here.
