I am a Lecturer in the School of Physics and Astronomy, Cardiff University. My areas of expertise are metal-organic chemical vapour deposition (MOCVD), selective-area epitaxy, advanced characterisation and emerging semiconductor devices. I am particularly interested in lattice mismatched growth of III-V photonic and electronic devices on silicon, a monolithic path towards future heterogeneous platforms. This involves developing a fundamental understanding of the nucleation process, crystal lattice engineering, defect study, and advanced materials characterization from macro- to nanometer-scale. My research activities are interdisciplinary. Rooted in material science, I am actively engaged in demonstrating novel device concepts as well as improving conventional devices in 3D geometries. In the past five years, I have published over 50 papers in top-notch international journals and conferences (Optica, OE, OL, APL, JAP, IEEE EDL, IEEE T-ED, IEDM, etc.), one pending US patent and one book chapter.

At Cardiff University, I am leading a newly established, MOCVD research lab. We have a brand new Aixtron Flip Top Close Coupled Showerhead (CCS) MOCVD system dedicated to III-As, III-P, and III-Sb growth on Si and III-V substrates. The unique CCS design allows an intrinsically uniform and reproducible growth for all the material systems of interest and provides a highly flexible process window for the deposition of a wide range of nano-structures (layers, fins, dots, wires). My group also works closely with the Institute for Compound Semiconductors (ICS) and The Future Compound Semiconductor Manufacturing Hub. We welcome all collaborators, both from academia and industry.

I received the B.S. degree in Microelectronics from Peking University, Beijing, China in 2009, and Ph.D. degree in Electronic and Computer Engineering (ECE) from The Hong Kong University of Science and Technology (HKUST) in 2014. Between 2014 and 2018, I was with the ECE Department of HKUST, first as a Research Associate (2014-2015), and then as a Research Assistant Professor (2015-2018). In March 2018 I joined Cardiff University as a Lecturer.
