Gigahertz frequency tuner based on a telescoping double-walled carbon nanotube: molecular dynamics simulations

Abstract

The schematics of a gigahertz-range tuner is addressed as an application of a telescoping multi-walled carbon nanotube (CNT) that can be used repeatedly, and its dynamic operation is investigated via classical molecular dynamics simulations based on a (5,5)(10,10) double-walled CNT. Fine control of the telescoped length of the double-walled CNT enables its resonance frequency to be matched to one of the signal frequencies, and the telescoped nanotube can be tuned to its resonance frequency for use as a component of a bandpass filter.
