Structural tuning of reduced exciton mass in layered HOIP compounds: Causation vs. correlation

Isaac R. Burkholder, Cindy Y. Wong, André Schleife +3

Reduced exciton mass ($\mu$) was recently reported to correlate strongly with a framework distortion in a series of nine single-layer (2D) metal-halide perovskite (HOIP) compounds. S…
