静电作用下碳纳米管阵列的参数共振

Parametric resonances in electrostatically interacting carbon nanotube arrays

A. Isacsson, J. M. Kinaret

摘要:

我们研究,数值和分析,在一个双端配置的一维阵列的碳纳米管谐振器的模型。系统在施加叠加在DC偏置电压上的AC信号时进入谐振。当阵列中的管彼此靠近时,管之间的静电相互作用对于阵列动力学变得重要。我们表明,横向和纵向参数共振可以激发除了主共振。管间静电相互作用耦合正交方向的模式,影响模式的稳定性。

英文摘要:

We study, numerically and analytically, a model of a one-dimensional array of carbon nanotube resonators in a two-terminal configuration. The system is brought into resonance upon application of an AC-signal superimposed on a DC-bias voltage. When the tubes in the array are close to each other, electrostatic interactions between tubes become important for the array dynamics. We show that both transverse and longitudinal parametric resonances can be excited in addition to primary resonances. The intertube electrostatic interactions couple modes in orthogonal directions and affect the mode stability.
