The additional degrees of dynamic freedom introduced by having an organic cation embedded in a three-dimensional lattice adds additional complexity to the structure, relative to totally inorganic or totally organic materials. How do these dynamics impact the optoelectronic, ferroelectric, or magnetic properties? The goal of this project is to develop design rules that can be generalized within and beyond this class of materials.

Many of the material we use for energy applications are based on decades-old understanding of materials. Intercalation battery chemistry, for example, still is based off of layered materials discovered 40 years ago. The goal of this project is to identify under-explored classes of materials that can be used for energy storage and conversion. Developing a wide library of materials for this application will generate more expansive, generalizable design principles.

Many of the materials we use in energy related fields have unpaired electrons, and are therefore magnetic. The goal of this project is to exploit the sensitivity of magnetometry to the behavior of electrons towards a better understanding of redox and phase behavior of energy relevant materials.
