We report on the characterization of nanometer-scale resonators. Each device incorporates one multiwalled carbon nanotube (MWNT) as a torsional spring. The devices are actuated electrostatically, and their deflections, both low frequency and on resonance, are detected optically. These are some of the smallest electromechanical devices ever created and are a demonstration of practical integrated MWNT-based oscillators. The results also show surprising intershell mechanical coupling behavior in the MWNTs.
我们报告了纳米级谐振器的特性。每个器件都包含一根多壁碳纳米管(MWNT)作为扭转弹簧。这些器件通过静电驱动,其低频和共振时的偏转通过光学方式检测。这些是有史以来制造出的一些最小的机电装置,展示了基于MWNT的实用集成振荡器。结果还显示了MWNT中令人惊讶的壳间机械耦合行为。
