	Abstract:	Fullerenes and carbon nanotubes are of considerable interest throughout many scientific areas due to their unique and exceptional properties, such as low weight, high strength, flexibility, high thermal conductivity and chemical stability. These nanostructures have many potential applications in nano-devices. One concept that has attracted much attention is the creation of nano-oscillators, which can produce frequencies in the gigahertz range, for applications such as ultra-fast optical filters and nano-antennae. In this paper, we provide the underlying mechanisms of the gigahertz nano-oscillators and we review some recent results derived by the authors using the Lennard-Jones potential together with the continuum approach to mathematically model three different types of nano-oscillators including double-walled carbon nanotube, C₆₀-nanotube and C₆₀-nanotorus oscillators.
	Keywords:	continuum modelling; gigahertz nanooscillators; double-walled carbon nanotubes; C₆₀ fullerenes; nanotorus oscillators; Lennard-Jones potential; nanotechnology; Australia; nanostructures; optical filters; nanoantennae.
