The group, led by Tianhong Cui at the University of Minnesota, US, has explored the fundamental issues of fabrication by characterizing the devices step by step. As a result, the scientists observed reduced electrical resistance of the stripe film pattern when thin-film was released. More importantly, the flexural Young's modulus they found using a nanoindentation technique was on the order of 500–800 GPa. The stiff CNT thin-film micropatterns and suspended beam architecture have a variety of potential applications including novel physical sensors, nanoelectromechanical switches and other M/NEMS devices.

The team is using the bridge-like structures for nanoswitch applications thanks to the electrically conductive nature and excellent mechanical stiffness of the material. The group has studied the lithography-compatible layer-by-layer nano self-assembly process in detail, and has previously configured nanomaterials as thin-film transistors and biosensors.

Additional information including a detailed version of the fabrication procedure is available in the journal Nanotechnology.
