2-dimensional transition metal dichalcogenide (TMDC) materials such as MoS2 have attracted much research interest for future electronics and optoelectronics due to their unique electrical properties. The optical and electronic properties of TMDC can vary depending on the number of layers. In this presentation, we report one can thin down the thicker layers of TMDC by illuminating laser. And, for monolayer MoS2, we could selectively deform the part of monolayer by using laser. The figure shown in the abstract presents a periodic modulation of the structure generated in the monolayer. We argue that the difference in the thermal expansion between substrate and the monolayer MoS2 can give rise to the mechanical deformation when shining laser. This strain engineering might provide a useful tool with enhancing the performance of electronic and optoelectronic devices based on TMDC materials. In addition, if time allows, we will report the magneto-transport of 2D TMDC materials probed up 60 T.
