Chenjian’s perspective article discussing charge transfer in 2D halide perovskites and 2D/3D heterostructures has been published in ACS Energy Letters. Congratulations!
In this Perspective, we address common terminological inaccuracies in energy level descriptions, delineate methods for energy alignment characterization, and present practical instances of CT in 2D perovskite-incorporated solar cells. Read the story here.
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.
