Abstract:
This study investigates the simultaneous decoration of vertically aligned molybdenum disulfide nanostructure (VA-MoS2) with Ag nanoparticles (NPs) and nitrogen functionalization. Nitrogen functionalization was achieved through physical vapor deposition (PVD) DC-magnetron sputtering using nitrogen as a reactive gas, aiming to induce p-type behavior in MoS2. The utilization of reactive sputtering resulted in the growth of three-dimensional silver structures on the surface of MoS2, promoting the formation of silver nanoparticles. A comprehensive characterization was conducted to assess surface modifications and analyze chemical and structural changes. X-ray photoelectron spectroscopy (XPS) showed the presence of silver on the MoS2 surface. Scanning electron microscopy (SEM) confirmed successful decoration with silver nanoparticles, showing that deposition time affects the size and distribution of the silver on the MoS2 surface.
摘要:
这项研究调查了垂直排列的二硫化钼纳米结构(VA-MoS2)与Ag纳米颗粒(NP)和氮官能化的同时装饰。使用氮气作为反应气体,通过物理气相沉积(PVD)直流磁控溅射实现氮气功能化,旨在诱导MoS2中的p型行为。利用反应溅射导致MoS2表面上三维银结构的生长,促进银纳米颗粒的形成。进行了全面表征以评估表面改性并分析化学和结构变化。X射线光电子能谱(XPS)显示在MoS2表面上存在银。扫描电子显微镜(SEM)证实了银纳米颗粒的成功装饰,表明沉积时间影响银在MoS2表面上的尺寸和分布。
