摘要：

We herein investigated surface acoustic wave (SAW) filters made of diamond and demonstrated that SAW resonators of 5 GHz band can be easily realized. Diamond has been previously studied for application in power devices and quantum computers. In particular, C-12 diamond has been applied to quantum computers using nitrogen-vacancy (NV) centers. We fabricated a SAW resonator for C-12 isotopically enriched diamond. Our resonator has a resonance frequency of 6 GHz and an anti-communicating frequency of 13 GHz. In the case of the Sezawa mode, the sound speed increased by 30%. We also found that the Young's modulus doubled with the removal of a small percentage of C-13. However, the reason for high coupling factor is yet to be discovered.
