摘要
为了研究飞秒激光脉冲数目与硅表面形貌之间的关系, 在相同的SF6气体氛围下, 改变照射硅表面的飞秒激光脉冲数, 发现在飞秒激光照射下由硅表面形成的微型锥状尖峰的高度与飞秒激光脉冲数呈现一种非线性关系。通过对该关系的研究有利于找出在制造具有较高吸收效率的高微型锥状尖峰的“黑硅”的实验条件, 有利于基于“黑硅”材料的光电器件转化效率的提高。
Abstract
To study the relationship between microstructuring of silicon and the number of femtosecond laser pulses, the number of femtosecond laser pulses irradiating the silicon is changed within the same atmosphere of SF6, it is find that there is a non-linear relationship between the height of the micro-cones and the number of femtosecond laser pulses. The study of this relationship is helpful to determine the experiment condition of fabricating “black silicon” with high micro-cones for high absorption, and the conversion efficiency of the electro-optical devices is improved.
