Laser printed two-dimensional transition metal dichalcogenides

Abstract Laser processing is a highly versatile technique for the post-synthesis treatment and modification of transition metal dichalcogenides (TMDCs). However, to date, TMDCs synthesis typically relies on large area CVD growth lithographic post-processing nanodevice fabrication, thus relying heavily complex, capital intensive, vacuum-based environments fabrication tools. This inflexibility necessarily restricts development facile, fast, very low-cost protocols. Here we show that direct, spatially selective 2D-TMDCs devices exhibit excellent electrical, Raman photoluminescence properties can be realized using laser printing under ambient conditions with minimal or thermal overheads. Our simple, elegant process scaled via conventional approaches including spatial light modulation digital engines enable mass production protocols such as roll-to-roll processing.
