Abstract

Because the properties of molybdenum disulfide (MoS₂) are strongly influenced by the sizes and boundaries of its domains, the direct visualization of large-area MoS₂ domains is one of the most important challenges in MoS₂ research. In the current study, we developed a simple and rapid method to observe and determine the boundaries of MoS₂ domains. The technique, which depends on observations of nematic liquid crystal textures on the MoS₂ surface, does not damage the sample and is not limited by domain size.
