Overview

At Cardiff University, I am leading a new MOCVD activity. A brand new Aixtron Flip Top Close Coupled Showerhead (CCS) MOCVD system was recently commissioned, 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 nanostructures (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.

We are looking for a postdoctoral researcher with expertise in MOCVD III-V growth to join the group! Please send your CV to LiQ44@cardiff.ac.uk if you are interested. 

Biography

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.

Research interest

My research covers various aspects around metal-organic chemical vapour deposition (MOCVD) of compound semiconductors for device applications. I am particularly interested in lattice-mismatched growth of III-V photonic and electronic devices on silicon, a monolithic path towards future heterogeneous platforms.
