Carbon nanotube is one of the best building blocks for future nano electro-mechanical systems especially in wireless communication application. It is originated from the excellent properties of carbon nanotubes such as high mechanical strength, chemical inertness, high aspect ratio, and good thermal conductivity. We directly fabricated laterally suspended carbon nanotube tunneling switch and studied its characteristics and performance as an electro-mechanical switch. The onset of tunneling turn-on voltage of carbon nanotube switch is as low as 2.6 V. The switching behavior of carbon nanotube electro-mechanical switch was modulated by a back gate voltage and investigated by in-situ Raman spectroscopy and impedance spectroscopy.
