Abstract

A simulation study of near-field enhancement on nanoprobe irradiated by annular laser beam is reported. Various nanofabrication, such as nano-welding, nano-manipulation and nano-etching, are produced on metal, semiconductor films and bulk by using the enhanced near-field underneath a probe irradiated by a laser beam. The simulation results show that comparing with the traditional single Gaussian beam, energy distribution of annular laser beam is much more uniform. The results indicate that near-field enhancement on nanoprobe irradiated by annular laser beam is much stronger than by single Gaussian beam. In addition, the relationship between wavelength and the field-induced effect such as temperature, stress and displacement in Z axis is explored. The results show that the shorter the wavelength, the higher the temperature of the probe and the greater the change in stress and deformation. Based on the simulation of the near field enhancement and the field-induced effect, a new scheme combining with annular laser beam and a nanoprobe is anticipated in nano-fabrication.

环形激光束辐照纳米探针近场增强及场致效应的数值模拟研究

本文报道了环形激光束辐照纳米探针的近场增强模拟研究。各种纳米加工，如纳米焊接、纳米操作和纳米蚀刻，在金属、半导体薄膜和体上生产，利用增强近场下的探头照射激光束。仿真结果表明，与传统的单高斯光束相比，环形激光束的能量分布更加均匀。结果表明，环形激光束对纳米探针的近场增强比单高斯光束强得多。此外，还探讨了波长与Z轴温度、应力、位移等场致效应的关系。结果表明，波长越短，探针温度越高，应力和变形变化越大。在模拟近场增强和场致效应的基础上，展望了环形激光束与纳米探针相结合的纳米加工新方案。
