Probing structure and bonding with electrons
We are located at the Stewart Blusson Quantum Matter Institute and Department of Physics & Astronomy at the University of British Columbia in Vancouver, BC, Canada.
We use scanning transmission electron microscopes (STEM) with high-energy-resolution electron energy loss spectroscopy (EELS) to achieve atomic-scale insights into structure, bonding and electron interactions in quantum materials. We incorporate ultra-stable cryogenic sample holders and in situ control knobs to simulataneously manipulate and visualize emergent phases in strongly correlated materials.
