同步纳米线机械谐振器中的调频自激振荡和相位惯性
Frequency modulated self-oscillation and phase inertia in a synchronized nanowire mechanical resonator
摘要：
同步已被广泛报道的自振荡系统。然而，尽管它已经在理论上预测了几十年，但在高驱动状态下的相位自振荡（有时称为相位捕获）的实验实现直到最近才被研究。我们详细研究了具有内反馈的同步场发射SiC纳米机电系统中的相位动力学。更丰富的相位行为已明确确定，这意味着相位调制和惯性。这种同步机制有望对理解相互作用的自振荡网络的动力学和在纳米尺度上产生频率调制信号产生影响
英文摘要：
Synchronization has been reported for a wide range of self-oscillating systems. However, even though it has been predicted theoretically for several decades, the experimental realization of phase self-oscillation, sometimes called phase trapping, in the high driving regime has been studied only recently. We explored in detail the phase dynamics in a synchronized field emission SiC nanoelectromechanical system with intrinsic feedback. A richer variety of phase behavior has been unambiguously identified, implying phase modulation and inertia. This synchronization regime is expected to have implications for the comprehension of the dynamics of interacting self-oscillating networks and for the generation of frequency modulated signals at the nanoscale
