My research focuses on semiconductor nanostructures and physics including MBE growth, semiconductor characterization and devices containing nanostructures

Q. D. Zhuang gained his Ph.D from the Institute of Semiconductors , Chinese Academy of Sciences in 1999 for research into the Molecular Beam Epitaxy (MBE) growth of low-dimensional compound semiconductors and the applications for infrared optoelectronics. Since then he worked at the Singapore Nanyang Technological University as a Research Fellow to investigate InAs/GaAs quantum dots photodetectors and lasers. In 2001, he joined MBE group at the University of Glasgow to exclusively exploit a new class semiconductor of dilute nitride for telecom VCSELs. During the time at the Univesity of Glasgow, he was also responsible for supplying wide range of high quality epitaxial wafers to commercial customers. He joined the Physics Department at Lancaster University in 2003 where he established the MBE Laboratory and since then has been leading group of Semiconductor Quantum Materials nad Devices. His current research focuses on epitaxy of semioconductor quantum materials and their device applications, as well as instrumentation such as laser-based spectroscopic technology for medical sensors and gas monitoring.

My research focuses on semiconductor nanostructures and physics including MBE growth, semiconductor characterization and devices containing nanostructures:

• MBE growth of compound semiconductor materials inclduing arsenide, antimonide, dilute nitride and nitrides and quantum structures including quantum dots, quantum rings, nanowires and superlattice.
• Droplet epitaxy of unique quantum dots inclduing GaAs/AlGaAs and GaSb/AlGaSb QDs.
• Semiconductor nanowires and integration with silicon and 2D materials for advanced nanophonics. 
• Fundamental studies of semiconductor quantum materials and devices using HRXRD, photoluminescence and micro-photoluminescence, electroluminescence.
• Advanced optoelectronic devices including VCSELs, Lasers, LEDs, and photovoltaic, thermo-photovoltaic and photodetectors.

PhD and Postdoctoral Opportunities

I am always looking for students with high academic records for PhD study (EPSRC DTA studentship, Overseas Studentship and LU Faculty Overseas Studentship). I also welcome high respect researchers for postdoctoral posts. Please feel free to contact me for details. 

Collaborations and Visitors

I established wide national and international collaborations including Nottingham University, Surrey University, Warwick University, and Shanghai Institute of Technical Physics CAS, University of Electronic Science and Technology of China, Sun-Yat-Sen University, Wroclaw University of Technology, Nanyang Technological University, Taiwan National University. In addition, I set up close industrial collaboration with Cascade Technologies Emerson, Lumentum, Gas Sensing Solutions Ltd and CST Global. I am keen to develop international collaborations and to host high respect researchers and scientists as Academic Visitors. During the last a few years, I had visitors from China, India and Russia. Please get in touch if you are interested.
