Research Focus

Leslie Schoop video interviewSome materials are not easily described with conventional, textbook, condensed matter physics laws. These quantum materials can exhibit exotic properties that could help improve information technology (for example: being able to build quantum computers). Additionally, they can be hosts of completely new physics and can even help to increase our understanding of the universe. New exciting phenomena are rapidly predicted by theoretical physicists. In order to study these properties, materials that fulfill the requirements need to be discovered first. This is where chemistry comes into play. Combining lessons from inorganic chemistry with electronic structure calculations gives predictive power to find these materials. After identifying interesting candidates, we will synthesize and characterize them.

Our group operates with the following procedure: First, inspiration comes from recognizing patterns in electronic structure, crystal structure, and properties of known materials. Then, this knowledge is used to find a compound that could be a starting point to realize a desired property in a new material. Chemical concepts about bonding and electron count are the most important tools for achieving this. Subsequently, the electronic structure is calculated  using available codes. If it confirms the initial idea, the material will be synthesized and characterized. To make the new materials, we use the combined knowledge of solid state chemistry, including methods such as flux growth, vapor transport, and Bridgman growth. Finally, if the crystal structure assumed for the electronic structure calculation and the real crystal structure match, the properties can be measured.
