The Wang group at the University of Minnesota (UMN) focuses on the basic science and engineering of energy transport in nanostructured materials and across nanoscale interfaces. We explore the mechanisms through which light (photons, electromagnetic waves), charge (movement of electrons), heat (vibration of crystalline lattices), and spin (angular momentum of electrons) are converted to useful forms of energy (e.g., electricity), and their applications (e.g., electronic cooling and data storage). To achieve this, we invent and implement state-of-the-art ultrafast measurement methods to reveal the rich physics of heat and spin transport, which enables us to better design and optimize materials with desirable functionalities.
- Ultrafast laser spectroscopy
- Thermal transport properties of materials (such as bulk, thin films, nanoparticles, and composites) and interfaces to (1) establish the structure-thermal property relationship and (2) design and synthesize functional materials via structural engineering
- Thermal management of electronic devices and electrical systems
- Solid-state energy conversion
- Spin precession and magnetization dynamics in magnetic materials for data storage and spintronic devices
