m-MoO2薄膜中厚度依赖的拉曼光谱研究
Thickness-dependent Raman Spectroscopy of m-MoO2 2D Flakes
摘要
Abstract
Monoclinic-phase molybdenum dioxide(m-MoO2)two-dimensional(2D)flakes exhibit outstanding prop-erties comparable to those of noble metals,with tunable performance depending on flake thickness.This makes it high-ly promising for applications in areas such as environmental monitoring and wastewater sensing.One of prerequisites for achieving high-performance MoO2-based devices is the development of an in-situ,rapid,and non-destructive method for measuring flake thickness.In this work,the dependence of the Raman spectra of MoO2 2D thin flakes on flake thickness is investigated,providing a method for in-situ,non-destructive thickness characterization.Excited with 532 nm laser,the shift in the Raman characteristic peak at 127 cm-1 effectively reflects the variation in flake thick-ness.Furthermore,by adjusting the polarization of the excitation light,the crystal axis orientation of the MoO2 thin flake can be calibrated.The Raman spectroscopic results thus offer an effective and convenient approach for monitor-ing the flake thickness in MoO2-based device fabrication.关键词
