Raman Spectroscopy for 2-Dimensional Materials Research

초록

Raman spectroscopy is a powerful tool to study various physical properties of 2-dimensional (2D) materials. It is routinely used to determine the number of layers, polytypes, and crystallographic directions and to estimate doping or strain in various 2D materials. Its use is further expanded to investigate magnetic ordering in ferromagnetic or antiferromagnetic materials. On the other hand, strong resonance effects induce peculiarities in the Raman spectra that are often misinterpreted by non-specialists. This tutorial is intended for people who use Raman spectroscopy or interpret Raman data in their research but are not Raman specialists. I will review some typical applications of Raman spectroscopy in 2D materials research with specific examples. © 2022 IEEE.
