Research Focus

Our new Quantum Materials Electron Microscopy Centre will have a state of the art electron microscope for atomic imaging and characterization of materials and for carrying out electron energy loss measurements as a function of momentum with ultra-high energy resolution. Research with this latter capability may include measurements of the momentum dependence of the dielectric function of quantum materials, studies of collective excitations in inhomogeneous strongly correlated matter, and studies of the spectrum of confined optical modes in polaritonic media. We are also developing a nanospectroscopy laboratory for conducting optical spectroscopy measurements. This will aid in discovery of new polaritonic materials based on 2D electrides and layered transition metal oxides, and developing means for controlling them by integrating them with quantum materials.
