This $208,120 federal Project Grant, awarded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) program, will support research on light-matter interaction in van der Waals heterostructures of atomically thin semiconductors conducted by Carnegie Mellon University (CMU). The primary objectives are to explore the unique light-matter interaction and emerging properties in individual and stacked atomically thin semiconductors, with the goal of improving the efficiency, speed, and functionality of future optoelectronic devices. The research will employ advanced optical spectroscopy techniques to study the many-body physics underlying exciton properties in monolayer transition metal dichalcogenides. The project will also investigate interlayer excitons in van der Waals heterostructure devices, including those with controlled twist angles to engineer moire potentials. This research aims to advance the fundamental understanding of light-matter interactions in two-dimensional quantum materials, ultimately leading to new capabilities for quantum optoelectronics. The award includes an integrated education component to train the next generation workforce in nanoscale science and engineering, with a focus on increasing participation of women and underrepresented groups.
