应变纳米机械谐振器最近通过耗散稀释现象实现了10亿的品质因数。值得注意的是，这些设备的潜力似乎还没有耗尽，每三年就呈现出大约一个数量级（infactor）的比例定律。本文回顾了导致这一点的进展，包括声子晶体的“软箝位”，应变工程，和极端纵横比的厘米级器件的趋势。最近的趋势包括应变晶体薄膜，分形图案的支持，和机器学习优化的支持调查。从这些进步中出现的新的可能性范围从无腔量子光学力学到超灵敏加速度计。
Strained nanomechanical resonators have recently achieved quality factors of 1 billion through the phenomenon of dissipation dilution. Remarkably, the potential of these devices seems unexhausted, exhibiting a scaling law of roughly one order of magnitude (infactor) every three years. This paper reviews advances which led to this point, including phononic crystal “soft-clamping,” strain engineering, and a trend towards centimeter-scale devices with extreme aspect ratios. Recent trends include investigation of strained crystalline thin films, fractal-patterned supports, and machine-learning-optimized supports. New possibilities emerging from these advances range from cavity free quantum optomechanics to ultra-sensitive accelerometry.
