Electronic Properties of Quantum Materials

Our lab investigates how electrons behave in solids — such as crystals, glasses, metals, superconductors, van-der-Waals (2D) materials, spin-liquid magnets, charge-ordered oxides and amorphous Anderson insulators — and the fundamental physical processes that generate them. Using both experimental and computational / numerical projects, we develop models for and new physical insight into the “baby universes” of solid materials. In the lab, we synthesize and study materials grown using a range of techniques, from scotch-tape exfoliation to atomic force microscopy and collaborations with world-class crystal growers, and then measure and model structural and electrical properties. We are looking for breakdowns in standard pictures (like Ohm’s law for electrical resistivity) that occur when quantum mechanics takes over, often in extreme conditions of reduced dimensions, low temperatures, intense magnetic fields, and high pressures!

Active and ongoing projects in the lab include (1) exfoliation and microscopic characterization of 2D “van der Waals” materials like graphene, (2) measurement and microscopic modeling of the electrical conductivity and Hall effect in inhomogeneous systems, and (3) examining the effects of disorder on phase-change materials for neuromorphic computing (in collaboration with RWTH Aachen University). Typical projects in the lab require more than one academic semester or summer of active work.

Note: No essay is required. You should EMAIL THE PI (Nicholas Breznay) to indicate your specific project interest(s) and availability, and to tour the lab.

Quantum Materials Laboratory
Why join this research group or lab?

You are excited to explore and understand how the physics and STEM concepts you learned in the classroom can be used to explain the “social structures” of electrons in solid materials. You are drawn to work on projects that are naturally collaborative, bridging the fields of physics, materials science, chemistry, and engineering! You are committed to ask questions and build conceptual models for the mini-universes of crystalline and disordered materials, and to systematically record and clearly communicate this work and your understanding. Our goal will be to present new-found understanding in the form of posters and conference presentations, peer-reviewed publications, and public outreach.
