Abstract Scope |
The rise of two-dimensional atomic crystals (2DACs) and van der Waals heterostructures (vdWHs) has inspired a bonding-free approach to constructing heterostructures beyond traditional epitaxial methods. This talk begins with an overview of early explorations into van der Waals (vdW) interactions for integrating disparate materials with pristine electronic interfaces. I will then focus on our recent advancements in synthesizing and exploring a diverse family of vdW superlattices (vdWSLs) composed of alternating layers of 2DACs and self-assembled molecular interlayers with customizable chemical compositions and structural motifs. I will highlight how these molecular interlayers can tailor the electronic and optical properties of 2DACs, with a particular emphasis on chiral molecular intercalation superlattices that exhibit robust chiral-induced spin selectivity and intriguing chiral superconductivity. With versatile molecular design and modular assembly strategies, 2D-molecular vdWSLs offer boundless opportunities to tailor electronic, optical, and quantum properties, creating a rich platform for emerging technologies. |
