Welcome to Q-squared Lab!


Emerging low-dimensional materials such as 2D van der Waals crystals, topological insulators, nanowires and quantum dots have been attracting significant attention in aspect of photonic, optoelectronic and magnetic applications because of their enhanced features and new functionalities. These functional properties offer unique platforms when they are coupled to photonic and plasmonic structures, enabling advanced applications such as photon sources, photodetectors, modulators, sensors and energy conversion devices. In our lab, we are pursuing a better understanding of fundamental physics of these new materials in order to overcome existing disadvantages and limitations, and developing novel and innovative photonics, opto-electronics, spintronics, and quantum information applications.
