摘要
单层二硫化钼(MoS2)具有直接带隙和优异的光电性能,在场效应晶体管、太阳能电池、光电探测器和气体传感器等领域有潜在的应用前景。本文采取常压化学气相沉积(APCVD)的方法在SiO2/Si衬底上生长了大尺寸的三角形MoS2纳米片。Raman谱、PL谱和光学衬度谱表明,所生长的MoS2样品为厚度均匀的单层MoS2,且具有较高的晶化质量和良好的发光性能。
Monolayer molybdenum disulfide (MoS2) has potential application potential in Field effect transistors, solar cells, photodetector and gas sensor due to its direct band gap and excellent photoelectric performance. In this paper, large triangular MoS2 nanosheets were grown on SiO2/Si substrate by atmospheric pressure chemical vapor deposition (APCVD). The results of Raman spectrum, PL spectrum and optical contrast spectrum show that the as-grown MoS2 nanosheets are monolayer of uniform thickness with good crystalline quality and good luminous properties.
