Since the discovery of new nanomaterials such as carbon nanotubes and graphene, due to their unique properties, researchers have tried a lot to find another new material that can outperform conventional materials. Recently, research on new materials such as transition metal dichalcogenides and tellurene, which are two-dimensional semiconductors, has been actively conducted. In addition, halide perovskite, which is used in photovoltaic devices, is also receiving a lot of attention. Research on such a new substance begins with finding a new physics hidden in it, and up to presenting applicability using the found physics. Our study aims to peek into new physics using novel spectroscopic equipment in emerging materials, and to present a perspective on applicability. In the presentation, I will introduce the research on emerging materials with tip enhanced Raman spectroscopy and IR nanoscopy. In addition, deep learning applied correlation spectroscopy approach for finding unknown physics will be provided.
