基于层间桥连碳纳米卷的超快纳米振荡器
Ultrafast nano-oscillators based on interlayer-bridged carbon nanoscrolls
摘要：
我们展示了一种可行的方法来制造超快轴向纳米振荡器的基础上碳纳米卷（CNSs）使用分子动力学模拟。由单壁碳纳米管（CNT）引发，单层石墨烯可以连续滚动到CNS中，CNT容纳在CNS中。CNS内部的CNT可以在10 s GHz的固有频率下沿轴向方向振荡。我们证明了一种有效的策略，以减少耗散的CNS为基础的纳米振荡器通过共价桥接的碳层在CNS。我们进一步证明，这种基于CNS的纳米振荡器可以被外部交流电场激励和驱动，并在超过100 GHz的振荡。基于CNS的纳米振荡器不仅提供了通向超快纳米器件的可行途径，而且还有望实现纳米级能量转换、利用和存储（例如，从电动到机械）。
英文摘要：
We demonstrate a viable approach to fabricating ultrafast axial nano-oscillators based on carbon nanoscrolls (CNSs) using molecular dynamics simulations. Initiated by a single-walled carbon nanotube (CNT), a monolayer graphene can continuously scroll into a CNS with the CNT housed inside. The CNT inside the CNS can oscillate along axial direction at a natural frequency of 10s gigahertz (GHz). We demonstrate an effective strategy to reduce the dissipation of the CNS-based nano-oscillator by covalently bridging the carbon layers in the CNS. We further demonstrate that, such a CNS-based nano-oscillator can be excited and driven by an external AC electric field, and oscillate at more than 100 GHz. The CNS-based nano-oscillators not only offer a feasible pathway toward ultrafast nano-devices, but also hold promise to enable nano-scale energy transduction, harnessing and storage (e.g., from electric to mechanical).
