摘要
一种新型光子力显微镜已经研制成功。通过使用纳米尺寸的掺杂镧系元素的受困晶体,实现了 110 aN 的最小检测力和低至 1.8 fN/\(\sqrt{\{rm{Hz}}) 的力灵敏度。这为物理科学中的力传感开辟了新的前景。
A material change for ultra-high precision force sensing
An original form of photonic force microscope has been developed. Operating with a trapped lanthanide-doped crystal of nanometric dimensions, a minimum detected force of the order of 110 aN and a force sensitivity down to 1.8 fN/\(\sqrt{{\rm{Hz}}}\) have been realised. This opens up new prospects for force sensing in the physical sciences.
