Abstract: By observing the LCs aligned along the crystalline orientation of 2D domains using polarized optical microscopy, the domain structures of 2D materials including graphene and molybdenum disulfide (MoS2) are easily visualized in a large area.?While it is impossible to observe the domain structure of 2D materials by optical microscopy due to the absence of optical contrast between each domain, birefringence colors from aligned liquid crsytals using POM succesfully reveal the domain structure of underlying materials. By using the advantages of our method, various growth factors affecting the crystallization of graphene during chemical vapor depostion?were investigated as well as the relationship between domain boundaries and electrical properties.
