摘要：
本文研究了超润滑表面上纳米颗粒的光学操控。研究揭示，由于超润滑界面具有近零的静摩擦和极低的动摩擦，控制光场的最大强度可低于100 W/cm$^2$，比传统界面上的纳米颗粒操控低九个数量级。受控纳米颗粒半径可小至5 nm，比传统光学操控的纳米颗粒小一个多数量级。操控可在亚微秒至微秒时间尺度内实现。此外，该操控发生在固体表面和非液体环境中，受布朗运动影响极小。通过适当增加动摩擦、控制光强或降低压力，可消除布朗运动的影响，从而构建尺寸小至光波长1/75的微结构。这实现了超分辨率光学微结构的控制。超润滑表面上纳米颗粒的光学超分辨率操控将在纳米加工、光刻、光学超表面和生化分析等领域找到重要应用。
英文摘要：
The optical manipulation of nanoparticles on superlubricity surfaces is investigated. The research revealed that, due to the near-zero static friction and extremely low dynamic friction at superlubricity interfaces, the maximum intensity for controlling the optical field can be less than 100 W/cm$^2$, which is nine orders of magnitude lower than controlling nanoparticles on traditional interfaces. The controlled nanoparticle radius can be as small as 5 nm, which is more than one order of magnitude smaller than nanoparticles controlled through traditional optical manipulation. Manipulation can be achieved in sub-microsecond to microsecond timescales. Furthermore, the manipulation takes place on solid surfaces and in non-liquid environments, with minimal impact from Brownian motion. By appropriately increasing dynamic friction, controlling light intensity, or reducing pressure, the effects of Brownian motion can be eliminated, allowing for the construction of microstructures with a size as small as 1/75 of the wavelength of light. This enables the control of super-resolution optical microstructures. The optical super-resolution manipulation of nanoparticles on superlubricity surfaces will find important applications in fields such as nanofabrication, photolithography, optical metasurface, and biochemical analysis.
