Casimir力作用下的石墨烯悬臂梁

Graphene Cantilever Under Casimir Force

Amel Derras-Chouk, Eugene Chudnovsky, Dmitry Garanin, Reem Jaafar

摘要:

研究了石墨烯悬臂梁在Casimir引力作用下的稳定性。得到了失稳阈值与温度和抗弯刚度的关系。通过临界温度的数值计算来补充分析工作,在该临界温度以上,石墨烯悬臂不可逆地向下弯曲并附着到导体。石墨烯片的附着和剥离的几何形状进行了讨论。有人认为,石墨烯悬臂梁可以是一个很好的工具,精确测量的卡西米尔力。

英文摘要:

Stability of graphene cantilever under Casimir attraction to an underlying conductor is investigated. The dependence of the instability threshold on temperature and flexural rigidity is obtained. Analytical work is supplemented by numerical computation of the critical temperature above which the graphene cantilever irreversibly bends down and attaches to the conductor. The geometry of the attachment and exfoliation of the graphene sheet is discussed. It is argued that graphene cantilever can be an excellent tool for precision measurements of the Casimir force.
