项目摘要

We have developed new bottom-up process for the fabrication of nanoparticle composite thin films in dusty plasma. We have obtained three main results. (i) We produced dust particles in reactive discharge plasma. The appearance of dust particles leaded to an increase in number density of Ar metastable atoms, and this is due to the drastic change of plasma parameters such as electron temperature. We also observed the void structure in dust-particle cloud, which is well explained by the effect of ion drag force acting on the dust particles. (ii) We succeeded in the transportation of dust particles by applying the external electric field. The dust particles dynamically moved from the bottom ion-sheath region to the upper substrate which is located more than 1 cm away from the bottom ion-sheath region. (iii) We deposited nanoparticle composite thin films, where crystalline Si nanoparticles of 6-11 nm diameter were produced in plasma, and they were successfully transported to the substrate.

我们开发了一种新的自下而上的工艺，用于在尘埃等离子体中制备纳米颗粒复合薄膜。我们得到了三个主要结果。(i)我们在反应放电等离子体中产生了尘埃颗粒。尘埃粒子的出现导致了Ar亚稳原子数密度的增加，这是由于等离子体参数如电子温度的剧烈变化。我们还观察到尘埃粒子云中的空洞结构，这是很好地解释了离子拖曳力的作用。(ii)我们利用外加电场成功地实现了尘埃粒子的输运。尘埃粒子动态地从底部离子鞘区移动到位于距离底部离子鞘区大于1cm的上基板。(iii)我们沉积纳米颗粒复合薄膜，其中在等离子体中产生6-11 nm直径的结晶Si纳米颗粒，并且它们被成功地传输到衬底。
