Designing Functional Emergence at the Interfaces of Metals

Atomically precise engineering of interfaces between dissimilar solids has led to numerous fundamental discoveries in condensed matter physics. Interfaces formed with insulators, such as oxides, and/or epitaxial semiconducting layers, have already been of great interest over decades, resulting in the field-effect devices or high-mobility electrons in semiconductor heterostructure, to topological phenomena, or even superconductivity with perovskite oxides. This talk will be on engineering emergent properties with a unique three-dimensional network of interfaces with bi-metallic core-shell hybrids, which can exhibit unprecedent enhancement in effective electron-lattice coupling, or giant Rashba spin-orbit effects, and even unconventional thermoelectric properties. I shall discuss possible impact of such a material engineering strategy on a variety of physical properties and phenomena.
