Valley Polarization-Electric Dipole Interference and Nonlinear Chiral Selection Rules in Monolayer WSe
Paul Herrmann, Sebastian Klimmer, Till Weickhardt +6
In monolayer transition metal dichalcogenides time-reversal symmetry, combined with space-inversion symmetry, defines the spin-valley degree of freedom. As such, engineering and co…
