Kai-Qiang Lin

Kai-Qiang Lin serves as Professor in the Department of Chemistry at Xiamen University's College of Chemistry and Chemical Engineering since 2023, following academic appointments at Germany's University of Regensburg (2018-2022). His research laboratory operates from Tan Kah Kee Innovation Laboratory Building (Room 2313).

Academic Background:

• B.S. in Chemistry, Xiamen University (2009-2013)
• Ph.D. in Physical Chemistry, Xiamen University (2013-2018)
• Postdoctoral Researcher, University of Regensburg (2018-2019)
• Akademischer Rat a.Z., University of Regensburg (2020-2022)

Research Focus: Dr. Lin pioneers experimental investigations of quantum optical phenomena in two-dimensional materials, specializing in ultrafast spectroscopy of excitonic systems. His work bridges quantum nonlinear optics and optoelectronics, with emphasis on valley-polarized trions, interlayer excitons, and twist-angle engineered heterostructures in transition metal dichalcogenides like WSe₂. This research enables breakthroughs in quantum information processing and nanoscale optoelectronic devices.

Publication Trends: His 9 recent papers (2017-2024) in Nature-family journals demonstrate consistent leadership in 2D material photonics, evolving from plasmonic sensing (2017) to ultraviolet excitonics (2024). Key thematic progression shows increasing focus on quantum interference effects and moiré superlattice engineering for controlling light-matter interactions at sub-nanometer scales.

Scientific Recognition:

• Walter-Schottky-Preis (2023)
• Invited to 69th Nobel Laureate Meeting, Lindau (2019)

Laboratory Operations: The LKQ Lab (lkqlab.xmu.edu.cn) maintains experimental facilities for ultrafast laser spectroscopy and low-temperature optical characterization, directing research on quantum optical phenomena in van der Waals heterostructures through international collaborations with groups in Germany, Japan, and the US.
