摘要：

Carbon nanotube (CNT)-based resonators exhibit high sensitivity in the mass detection domain, but the difficulty in tuning the resonant characteristics restricts its application. In this paper, we investigate the resonance characteristics and intrinsic dissipation of a CNT and boron nitride nanotube (BNNT) coaxial heterostructure (CNT@BNNT) via molecular dynamics simulations. Compared with the CNT, the resonance characteristics and intrinsic dissipation of CNT@BNNT change with the axial strain variation induced by the electric field. In addition, the intrinsic dissipation of CNT@BNNT is much lower than that of BNNT due to the interlayer binding and the incommensurate interlayer lattice matching. Besides, the mass resolution of the CNT@BNNT-based resonator exhibits up to 38.9 yg (1 yg = 10(-24) g) at room temperature, comparable to that of the CNT-based resonator. These interesting features indicate that CNT@BNNT is a piezoelectrically tunable resonator with excellent mass sensitivity.
