Control of carbon nanotube cantilever vibrator for nano-antenna applications

The cantilever vibrator motion system of a carbon nanotube (CNT) is considered the next step in developing cold cathodes for VHF-band nano-antennas. In cases where a nano-antenna is used in noisy environments, this device interferes with other communication devices. In this paper, both the mechanica...
