For its first 10 years, the atomically thin 2D materials community was largely unified in its choice of materials, first with graphene and more recently with 2D semiconductors, primarily transition metal dichalcogenides and black phosphorus. An explosion in the availability of diverse 2D materials, combined with a relatively short attention span of the community lead to the question, what now? In this talk, I will describe two ways that my lab is approaching 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 add the possibility of gate-controlled ferromagnetism to the 2D material toolbox.
