Spectroscopy and Optoelectronics Lab
Probing the physics of low-dimensional materials with light, and turning it into optoelectronic devices.
We explore the fundamental physical properties of novel low-dimensional materials using spectroscopic techniques such as Raman, photoluminescence and ultrafast spectroscopy, modulate their optoelectronic properties through defect, strain and interface engineering, and develop high-performance photodetectors, light-emitting and photovoltaic devices.
