About
Prof. Leng's research group at the Department of Applied Physics, PolyU focuses on the chemical design, synthesis, growth, physics and Nano&Micro device applications of low-dimensional materials such as organic-inorganic hybrid 2D materials.
Prof. Leng has been appointed as the Director of the JC STEM Lab for 2D Quantum Materials from April 2026.
