Research Interests

We use and develop advanced optical spectroscopies to investigate ultrafast phenomena and optical properties in novel materials. Experimental tools include pump-probe spectroscopy, transient grating spectroscopy, spin noise spectroscopy, photoluminescence, second-harmonic generation, etc. Current fields of research include atomically-thin transition metal dichalcogenides and other low-dimensional nanostructures.

We recruit highly-motivated undergraduates, PhD students and postdocs every year. Please contact Prof. Yang (luyi-yang(at)mail.tsinghua.edu.cn) for details.
