Li Yang, professor of physics, was awarded a 3-year $375,000 grant titled “Doping Effects on Excited-State Properties of Two-Dimensional Moiré Crystals” from the National Science Foundation to explore novel many-electron interactions and optical properties of two-dimensional moiré crystals, a family of emerging quantum materials formed by stacking two atomic layers with a twisting angle. The proposal aims at tuning electronic and photonic properties of artificial moiré crystals and realizing the “programmable” quantum emitters that are fundamental elements for quantum-information and quantum-sensor applications.
