摘要
利用800nm飞秒激光光镊捕获了水中分散的银纳米颗粒,在玻璃基片表面直写银线,通过调控激光参数研究了激光功率对银线线宽及表面形貌的影响,实现了线宽为378nm的银线直写。经过测试,直写的银线电阻率为固体银的19.88倍。此外,还利用该方法制备了银二维网格结构,体现了该技术在二维结构直写方面的良好加工能力。
A 800 nm femtosecond laser tweezer can be used to capture the silver nanoparticles dispersed in water and the silver wires are directly written on the glass substrate.The influences of laser power on the silver wire width and surface morphology are investigated by adjusting laser parameters.The direct writing of silver wires with a width of378 nm is realized.After tests,the electrical resistivity of the fabricated silver wire is 19.88 times that of bulk silver.In addition,a two-dimensional(2D)silver grid structure is fabricated by this technique,which manifests that this technique possesses a good process ability in the field of 2D structure direct writing.
