Axially tunable carbon nanotube resonators using co-integrated microactuators.
Tuning of the mechanical resonance frequency of single-walled carbon nanotubes (SWCNTs) is achieved by application of uniaxial strain by purely mechanical means, utilizing both directly grown and dry-transferred SWCNTs. The induction of a beam-to-string transition is achieved, resulting in an axial tension sensitivity of 9.4 × 10(10) Hz/ε in the vibrating string regime. Increases in the resonant Q-factor, removal of residual slack, and resonance frequency changes from 10 to 60 MHz are affected.
