About

Dr. Leng's research group at the Department of Applied Physics, PolyU focuses on the chemical design, synthesis, physics and Nano&Micro device applications of low-dimensional materials such as organic-inorganic hybrid 2D materials.  

What's New

  • Our recent research work about surface octahedral tilt in 2D perovskites has been published (Nature Communications, 13, 138 (2022)).

  • Our recent perspective of Organic-inorganic hybrid perovskites and their heterostructures has beenpublished (Matter, 5, 4153-4169 (2022)). 

  • Our hot paper of Molecularly-thin, two-dimensional all-organic perovskites has been published (Science, 384, 60-66 (2024)).
