Shuchen’s paper about Moiré superlattices in twisted two-dimensional halide perovskites has been published in Nature Materials. Another exciting collaboration with Huang group. Congratulations!
We introduce perovskite moiré superlattices leveraging ultrathin, ligand-free halide perovskites, facilitated by ionic interactions. Twist-angle-dependent transient photoluminescence microscopy and electrical characterizations indicate the emergence of localized bright excitons and trapped charge carriers near a twist angle of ~10°. The localized excitons are accompanied by enhanced exciton emission, attributed to an increased oscillator strength by a theoretically predicted flat band. Read the story here.
