| 7371696 | Carbon nanotube structure and method of vertically aligning carbon nanotubes A Carbon NanoTube (CNT) structure includes a substrate, a CNT support layer, and a plurality of CNTs. The CNT support layer is stacked on the substrate and has pores therein. One end of each of the CNTs is attached to portions of the substrate exposed through the po... | 05/13/2008 |
| 7332736 | Article comprising gated field emission structures with centralized nanowires and method for making the same This invention provides novel methods of fabricating novel gated field emission structures that include aligned nanowire electron emitters (individually or in small groups) localized in central regions within gate apertures. It also provides novel devices using nano... | 02/19/2008 |
| 7316982 | Controlling carbon nanotubes using optical traps An embodiment of the present invention is a technique to control carbon nanotubes (CNTs). A laser beam is focused to a carbon nanotube (CNT) in a fluid. The CNT is responsive to a trapping frequency. The CNT is manipulated by controlling the focused laser beam. ... | 01/08/2008 |
