Research in the Jin group focuses on the rational synthesis, fundamental understanding, and physical properties of nanoscale and solid-state materials to address the challenges in renewable energy, information technology, and biomedicine. We have pioneered dislocation-driven nanomaterial growth and developed the innovative synthesis of nanomaterials including metal silicides, chalcogenides, and halide perovskites. Building on a better understanding of novel physical properties, we advance the exploitation of (nano)materials for electrocatalysis, energy conversion, and storage, optoelectronics, spintronics, and biotechnology. Our energy research aims to overcome the intermittency challenge of renewable energy by using earth-abundant materials.
