WELCOME TO THE LEE LAB
We are crystal engineers addressing critical issues of climate change and sustainable energy through materials discovery. By control the sizes, orientations, and structures of nanocrystals that can convert sunlight into electricity, we are improving the performance of next-generation optoelectronics for solar energy harvesting, photodetection, and sensing.

Nanoporous scaffolds can direct the orientation and size of crystals during solution-phase deposition to form nanowire arrays for high surface areas for optoelectronic processes. We are exploring scaffold-directed crystallization of small-molecule and halide perovskite nanowires for solar energy harvesting

Crystal twisting introduces periodicity to optoelectronic properties in organic semiconductor films and leads to wholly new properties, such as circular birefringence and dichroism. We are exploring crystal twisting in organic semiconductor films for chirooptoelectronics

Nanoconfinement can improve the stability of metal halide perovskites against temperature-induced polymorph transitions and environmental degradation. We are exploring nanoconfined perovskite crystals in scaffolds and electrospun fibers for stable, high performance optoelectronics
