2D Materials: What Now?

The atomically thin 2D materials community has so far been largely unified in its choice of materials, first with graphene and more recently with 2D semiconductors, primarily transition metal dichalcogenides and black phosphorus. A recent explosion in the availability of diverse 2D materials leads to the question, what now? In my lab, we are pursuing two answers to this question: first, to select the most compelling properties of more well-known materials to target particular physical effects or device types; and second, to investigate new materials that may add to the list of things that can be done with 2D materials and their heterostructures. In the first category, we are making gate-defined quantum dots based on transition metal dichalcogenides and exploring excitonic effects in black phosphorus heterostructures. In the second category, we are investigating layered group-IV monochalcogenides, which are potential multiferroic phase-change materials, and layered transition metal thiophosphates, which may provide gate-controlled ferromagnetism.
