空间分离的FePS $_3$纳米鼓之间机械共振的可调谐强耦合
Tunable strong coupling of mechanical resonance between spatially separated FePS$_3$ nanodrums
摘要：
由二维材料制成的耦合纳米机械谐振器在机械模式信息处理方面具有广阔的应用前景。然而，这些类型的系统的挑战是控制耦合。在这里，我们展示了磁性二维材料FePS $_3$的两个悬浮膜之间的运动的强耦合。我们描述了一种可调机电机制，用于控制谐振频率和耦合强度，使用每个膜下的栅极电压电极。我们表明，耦合可用于通过幅度调制将数据从一个鼓传输到另一个鼓。最后，我们还研究了耦合的温度依赖性，特别是它是如何受到这种材料的反铁磁相变特性。所提出的共振磁性2D膜的电耦合有望在低电功率下远距离传输机械能，从而实现新颖的数据读出和信息处理技术。
英文摘要：
Coupled nanomechanical resonators made of two-dimensional materials are promising for processing information with mechanical modes. However, the challenge for these types of systems is to control the coupling. Here, we demonstrate strong coupling of motion between two suspended membranes of the magnetic 2D material FePS$_3$. We describe a tunable electromechanical mechanism for control over both the resonance frequency and the coupling strength using a gate voltage electrode under each membrane. We show that the coupling can be utilized for transferring data from one drum to the other by amplitude modulation. Finally, we also study the temperature dependence of the coupling, and in particular how it is affected by the antiferromagnetic phase transition characteristic of this material. The presented electrical coupling of resonant magnetic 2D membranes holds promise of transferring mechanical energy over a distance at low electrical power, thus enabling novel data readout and information processing technologies.
