| Outline of Final Research Achievements |
We investigated mechanism of nonlinear responses of nanocarbon mechanical resonators, where experimental results obtained were analyzed by means of molecular dynamics simulations and finite element methods. As a result, we successfully demonstrated the improvement of the quality factor and the control of nonlinearity of the mechanical resonance of the nanocarbon resonator by introducing the additional potential fields such as van-der-Waals or electrostatic potential fields with retardation effect, which acts on the dissipation part of the resonant system and greatly reduces the apparent dissipation. The improvement of the apparent Q-factor and the change of the nonlinearity are expected to contribute to the improvement of sensitivity of nanomechanical-resonator based sensors and the development of novel nano-electro-mechanical devices.
