论文摘要
我们在超低温度下模拟并实验证明了石英的方向的存在，该方向可最大程度地减少表面声波（SAW）谐振器中的衍射损失。该方向是针对用于量子技术的应用，这些技术受益于高机械质量因素，强大的机电耦合和狭窄的声孔。我们在该基材上构造了狭窄的光圈，并在MK温度下测量超过100,000的内部质量因素。
We simulate and experimentally demonstrate the existence of an orientation of quartz which minimizes diffraction losses in surface acoustic wave (SAW) resonators at ultra-low temperatures. The orientation is optimized for applications to quantum technologies which benefit from high mechanical quality factors, strong electromechanical coupling, and narrow acoustic apertures. We fabricate narrow aperture SAW resonators on this substrate and measure internal quality factors greater than 100,000 at mK temperatures.
