Abstract:
For some systems, energy from an external source can trigger changes in the internal state of the structure, leading to a mechanical response much larger than the initial input. The ability to unlock this internal work in solid state materials is of key importance for many potential applications. Carbon Carbon nanotubes have been known to show highly interesting properties such as high mechanical strength, thermal conductivity, high optical absorbance, photoconductivity, and light emission. While there have been tremendous advances in many of these areas, the ability of nanotubes to absorb light and convert into mechanical, thermal, electrostatic and optical energy is still a poorly understood problem and could potentially open up many new applications from micro-robotics to cancer nanotechnology. This talk will focus on how the mechanical actuation of nanotubes is coupled with its electronic structure. Further new patterning process of nanotubes that enable the construction of MEMS structures based on nanotubes that out perform their MEMS electrical counterparts at a fraction of the optical energy will be demonstrated.
