摘要:

本论文阐明的物理机制,占的主要/主要阶段的结构化过程中发生的多个相同的飞秒激光脉冲照射的导电固体,基于考虑的混合理论模型。热传递与流体动力学模拟表明,它是可能的,以创建形态变化的条件下,仅利用毛细管效应,在没有任何非热熔化或蒸发。模拟结果,实验证实,揭示了中间表面改性阶段作为一个前身的微锥形成。

英文摘要:

The present paper elucidates the physical mechanism that accounts for the principal/primary stages of the structuring process taking place upon irradiation of a conductive solid with multiple identical femtosecond laser pulses, based on the consideration of a hybrid theoretical model. Heat transfer along with hydrodynamics simulations demonstrate that it is possible to create morphology change conditions by solely exploiting capillary effects, in the absence of either non-thermal melting or evaporation. Simulation results, confirmed by experiments, reveal the intermediate surface modification stage acting as a predecessor of microcones formation.
