ARCHITECTURING ATOMICALLY-THIN MATERIALS FOR MULTIFUNTIONALITY

Materials with designed structural features, such as layers, crumples, folds or ridges (i.e., architectured materials), are rapidly emerging as an exciting class of materials with new, adaptive, and multifunctional properties. The limitless combinations of design and control of structural features in materials enable the reconfigurable programming and integration of optical, thermal, electrical and mechanical functionalities. Atomically-thin material systems, such as graphene and transition metal dichalcogenide monolayers, have proven to be particularly attractive subject materials for architecturing due to their unique intrinsic properties, stackable nature, and ultralow bending stiffness. Mechanically controlled architecturing of atomically-thin materials allows new structural properties and device-level functionalities which surpass the limits of bulk material systems. In this talk, I will present our nano-manufacturing techniques in controlling deformation and straining of atomically-thin materials, and introduce the new and reconfigurable materials properties and applications of such deformed and strained materials. First, I will introduce shrink-manufacturing approaches to enabling controlled deformation of atomically-thin materials. Second, I will introduce a wide range of new functionalities of these architectured materials, such as shape-induced plasmonic resonance and strain-induced exciton funnelling and flexoelectricity. Third, I will present our work on adaptive and multifunctional devices based on architectured atomicallythin materials. Finally, I will share our vision for manufacturing and integration of architectured constituents toward layered, multi-dimensional systems. Our approach to designing and manufacturing architectured atomically-thin materials offers a unique avenue for enabling new materials properties and engineering of advanced device functions.
