Professor LEE Takhee (Dept. of Physics)

Professor LEE Takhee’s research team (Department of Physics and Astronomy) has succeeded in creating a thin film electronic element using molybdenum disulphide (MoS₂). MoS₂ is only a single atomic layer thick and possesses the characteristics of a semiconductor. The research team used chemical vapor deposition (CVD) to create a broad layer, several centimeters in width, of electronic elements. To distribute MoS₂ exactly where they wanted it, the team made use of a ‘shadow mask’ -- a board with holes. This way, further post-patterning processes can be avoided. Professor LEE stated that this research “increased the possibility of utilizing very thin semiconductor materials.”
