| 摘要 |
The present invention relates to a method for optical visualization of graphene domains, and more particularly to a method for optical visualization of graphene domains, which can optically visualize the domains and domain boundaries of graphene by forming on a substrate a graphene layer to be measured, forming a liquid crystal layer on the formed graphene layer, and then measuring the optical properties of the formed nematic liquid crystal layer. The method for optical visualization of graphene domains according to the invention uses a liquid crystal-coating method, which is simpler and easier than a conventional method for observing graphene domains. Thus, the method of the invention is simple, time-saving and inexpensive and, at the same time, enables very-large-area graphene domains to be observed with a polarizing microscope or the like. Therefore, the inventive method will be very useful in the research of graphene's properties.
