Quantum Materials
About
Alannah Hallas uses the tools of chemistry and materials science to design new quantum materials and then bring them into reality through crystal growth. Her group makes use of a wide range of crystal growth techniques that allow them to grow crystals under extreme temperatures, pressures, and gas environments, and even to see the crystal as it is growing in real time. Once a new material has been grown, Hallas and her team seek to uncover the structure-function relationships in these quantum materials using a combination of neutrons, muons, and x-rays. These probes provide direct insights into the electronic and magnetic behaviours exhibited by these quantum materials. In particular, she is interested in how disorder – in both miniscule and extreme concentrations – influences the states of quantum materials. Harnessing disorder may pave the way to quantum materials being used in a wide range of technological applications.
