在这项工作中，我们提出的超导纳米机械谐振器的制造和表征纳米掺硼金刚石（BDD）。振荡器可以在其超导状态下被驱动和读出，并且在大约10 MHz的谐振频率下显示出高达40，000的品质因数。机械阻尼的研究磁场高达3 T的谐振器仍然表现出超导性能。由于其简单的制造过程，这些设备可以很容易地耦合到其他超导电路，其性能与最先进的技术相当。(C)2014爱思唯尔有限公司版权所有。
In this work we present the fabrication and characterization of superconducting nano-mechanical resonators made from nanocrystalline boron doped diamond (BDD). The oscillators can be driven and read out in their superconducting state and show quality factors as high as 40,000 at a resonance frequency of around 10 MHz. Mechanical damping is studied for magnetic fields up to 3 T where the resonators still show superconducting properties. Due to their simple fabrication procedure, the devices can easily be coupled to other superconducting circuits and their performance is comparable with state-of-the-art technology.
