Monolayer graphene produced by chemical vapor deposition (CVD) has been studied with photoelectron momentum microscope (PMM). We could visualize the domain boundary in terms of the electronic states, such as the momentum map at the K point. In general, visualization of the domain boundary on a CVD monolayer graphene is considered as a formidable task.For example, it is difficult to visualize it using atomic force microscope (AFM). We propose a simple method of the visualization by the deposition of organic molecules such as phthalocyanine and oligothiophene. We report on these methods as the visualization of the domain boundary.
