5. 발표 내용

 Two-dimensional (2D) van der Waals semiconductors have various potentials for optoelectronic applications, 

owing to their unique optical and electrical properties at an atomic layer thickness. A stable excitonic emission 

of monolayer 2D semiconductors at room temperature, owing to a reduced dielectric screening effect, opens 

new research fields on excitonics and valleytronics. Moreover, their low dimensionality without surface dangling 

bonds allows for unique quantum transport phenomena via artificial van der Waals stacking using a versatile 

library of 2D materials. In this talk, the author introduces tunable quantum optoelectronic properties of 2D 

semiconductors by manipulating native defects, van der Waals interfaces, Coulomb interactions, plasmonic 

hybridizations, etc. Furthermore, the author reviews electronic and optoelectronic applications utilizing such 

unique tunable properties of 2D semiconductors.
