Printable photonics

Research at the National University of Singapore led by Loh Kian Ping has successfully developed a way to chemically exfoliate molybdenum disulfide crystals to make high-quality monolayer flakes. The high-yielding method for exfoliated flakes could be exploited to create an ink-like material that could be used to print photonics and electronic devices using nothing more elaborate than a modified inkjet printer. The same technique should work with other two-dimensional chalcogenide materials including tungsten diselenide and titanium disulfide. The NUS team collaborated with scientists from the Ulsan National Institute of Science and Technology in Korea.
