3D world. However, this efficiency must be improved a lot for any practical applications with the light emitted from the 2D materials. Our results on the energy transfer across the junctions of 2D materials provide an effective mechanism to increase the net absorption of light in a monolayer by just stacking it on the right material and thus improve the efficiency of light harvesting with 2D materials. Also, we can create artificial cavities by stacking appropriate materials to create a mirror-like effect to trap more light into a monolayer to further enhance the efficiency.
We are currently working on designing

devices with junctions of 2D materials harnessing the treasures of these different processes of charge and energy transfer happening at ultra-fast timescale of pico- seconds (10-12 s). However, the practical applications of semiconductor devices based on 2D materials are still limited by challenges of scalability of these devices, problems of material growth and inherent defects. But soon enough, the flatland would mark a place in the map of commercial market for several demanding applications like sensors for internet of things, energy harvesting and flexible electronics.
