MSE Areas: Superconductors, magnetic materials, neutron scattering, lattice dynamics, Raman spectroscopy
The research program of the Reznik group focuses on Fe and Cu-based high temperature supercondcutors, electron-phonon coupling, manganites, unusual magnets, correlated electrons, polarons in photovoltaics and other energy technology materials. The main tools to investigate these materials are neutron, x-ray and Raman scattering. The group was recently awarded a grant from the NFS Material Reseach Instrumentation program to construct a state-of the art time-resolved Raman scattering lab, which is now close to completion.
