Description
Topological semimetals display a range of novel transport phenomena, including enormous magnetoresistance and mobilities. Using Raman spectroscopy we have uncovered a novel mechanism for phonons to play a central role in this phenomena. Specifically we demonstrate the phonon-electron scattering time far exceeds the phonon-phonon. As such the momentum and energy typically lost to the lattice is returned to the electron bath. I will also briefly discuss the key material properties that make this discovery possible.
