Research Expertise 2D materials, optoelectronics, optical spectroscopy NEW MATERIALS SOLUTIONS FABRICATION AND PROCESSING ADVANCED INTERCONNECTS/DIELECTRICS METROLOGY Research We integrate material synthesis with state-of-art nanofabrication techniques to create structures or devices with control down to nanometer resolution. These structures and devices provide unique platforms to study electron-electron interactions, and electron-photon interactions.
