MateriAlZ Seminar: “Tailoring Layered Materials: From Hybrid Structures to Attosecond Dynamics”

Abstract: Van der Waals layered materials offer unprecedented opportunities for atomic-scale engineering of heterostructures with suggested functionalities ranging from topological quantum computing to optoelectronics. Research has largely concentrated on beautiful assemblies of 2D materials into tailormade low-dimensional heterostructures. Here, I will show how the combination of van der Waals layered materials with select organic semiconductors adds to the toolbox for creating novel heterostructures, and how new electronic properties with considerable potential for tailored functionalities, may be obtained.

In order to expand the materials design toolbox, I will demonstrate how 3D layered materials can be made 2D  by appropriate functionalization, paving the way for the large-area low-dimensional heterostructures. Finally, I will discuss how seemingly 3D materials are in fact 2D on timescales of 10^-15s, providing the benefits of quantum confinement on short timescales.
