不同厚度二维层状SnSe2纳米材料的拉曼光谱研究

摘要

In this paper,the Raman spectra of SnSe2 materials with different layers were measured.The relationship between the change of Raman peak intensities and positions in different vibrational modes and the corresponding SnSe2 samples with different thickness was obtained,and the reasons for the change were further analyzed.This research can provide a more systematic,accurate and rapid method for judging two dimensional SnSe2 materials.%本文研究了不同层数的SnSe2材料的拉曼光谱,通过对测试结果的分析得到不同振动模式的峰强及峰位的变化与不同厚度的SnSe2样品之间的对应关系,并进一步分析了变化的原因.该研究成果为二维SnSe2的研究提供了更加系统、准确、快捷的判断方法和手段.
