摘要:

我们报道了自下而上的纳机电系统(NEMS)在恒定外加电压驱动的场发射过程中观察到的自振荡。探索机电模型,解释的现象,可以直接用于开发集成器件。在第一项研究中,我们已经实现了约50%的DC/AC(直流到交流电)转换。NEMS中的电自振荡为高速自主纳米谐振器和信号发生器的发展开辟了一条新的道路,并表明场发射(FE)是构建新纳米元件的强大工具。

英文摘要:

We report the observation of self-oscillations in a bottom-up nanoelectromechanical system (NEMS) during field emission driven by a constant applied voltage. An electromechanical model is explored that explains the phenomenon and that can be directly used to develop integrated devices. In this first study we have already achieved ~50% DC/AC (direct to alternative current) conversion. Electrical self-oscillations in NEMS open up a new path for the development of high speed, autonomous nanoresonators, and signal generators and show that field emission (FE) is a powerful tool for building new nano-components.
