Within this class of materials, semiconducting transition metal dichalcogenides (TMDs) such as MoS<sub>2<\/sub> and WSe<sub>2<\/sub> have attracted significant interest in condensed matter physics and next generation electronics and optoelectronics. At the single layer limit, the TMDs exhibit direct band gaps which results in efficient light emission and retain good carrier mobility compared to conventional semiconductors such as silicon. Furthermore, TMD layers with different compositions and properties can be stacked to create unique heterostructures. \u00a0Practical device applications, however, require large area single layer TMD films which presents unique challenges. Our work has focused on the development of metalorganic chemical vapor deposition as a manufacturing-compatible approach for wafer-scale semiconducting TMDs. Applications of large area TMD films in photonics and nanoelectronics will be highlighted.<\/p>\n<p><strong>Joan Redwing <\/strong>is a Distinguished Professor of Materials Science and Engineering and Electrical Engineering at Penn State University.
