Functional 1.6 GHZ MEMS switch using aligned composite CNT membrane by dielectrophoretic self-assembly

This paper demonstrates fixed-beam switches using well-aligned composite SWNT membranes, which were prepared by dielectrophoretic process with Layer-by-Layer self-assembly. The measured DC pull-in voltages ranged from 0.9 V to 4.8 V, depending on the length of switches. AC measurements indicate a switching delay as low as 600 psec for 300 nm beams. This new SWNT composite membrane switch is promising for a variety of applications to high-end nanoelectronics and high- performance MEMS/NEMS.
