W explore a large family of van der Waals 2D materials for their widely ranging electronic, optical, magnetic, valleytronic and spintronic properties. We work with collaborators inside and outside Penn State to understand fundamental material properties, underlying mechanisms of device operations and discover new strategies of augmenting pristine materials through doping, alloying and heterostructure formation to engineer new properties and device functionalities.
