Abstract

Pulsed laser deposition (PLD) under gas atmospheres has been used to fabricate thin films for various applications. In this study, PLD was performed under various gas atmospheres (helium, oxygen, and argon) using tungsten (W) to investigate the morphology of thin films. Various types of structures were formed, including uniform, nanoparticles, and columnar structures. In particular, the substrate fabricated at an argon pressure of 100 Pa had a high porosity and a low light reflectance in the 200–1400 nm wavelength range. In addition, it was shown that the growth of the thin film thickness was non-linear with respect to time, and the formation of a fuzz-like structure may be influenced by particle diffusion in the gas phase and on the substrate.

不同气体环境下脉冲激光沉积钨多孔薄膜的形成条件

气体环境下的脉冲激光沉积（PLD）已被用于制造各种用途的薄膜。本研究使用钨（W）在各种气体环境（氦气、氧气和氩气）下进行了脉冲激光沉积，以研究薄膜的形态。形成了各种类型的结构，包括均匀结构、纳米颗粒结构和柱状结构。特别是在氩气压力为 100 Pa 时制造的基底具有高孔隙率和 200-1400 nm 波长范围内的低光反射率。此外，研究还表明，薄膜厚度的增长与时间呈非线性关系，绒毛状结构的形成可能受到气相中和基底上颗粒扩散的影响。
