Two-dimensional crystals (2DX) represented by graphene hold substantial potentials both in fundamental research and industrial applications owing to their novel electronic and optical properties originating from dimensional confinement. In addition, their intrinsic properties are readily manipulated by chemical entities in direct contact because of their high fraction of surface atoms. To uncover and control emerging properties, my group has explored surface and interfacial science of low dimensional materials using various spectroscopic methods. Raman and photoluminescence spectroscopy, in particular, have proven to be versatile analytical probes because of their varying spectral features for different thickness, stacking, defect density, charge density, mechanical strain, temperature, etc. In this talk, I will share our past endeavor to understand important surface scientific problems in 2-dimension such as structural deformation caused by substrates and thermal perturbation, interfacial charge transfer, and molecular diffusion through 2DX-substrate interface.
