Terahertz lattice and charge dynamics in ferroelectric semiconductor Sn x Pb1−x Te
Abstract The symmetry breaking induced by the ferroelectric transition often triggers the emergence of topological electronic states such as Weyl fermions in polar metals/semimetals. Such strong coupling between the lattice deformation and electronic states is therefore essentially important for the...
