Efficiency of THz spintronic emitters: from spin-Hall effect in 3d/5d transition metals to surface states of topological insulators
2021
THz spintronics emitters represent today novel sources for broadband emission using nanometer-scaled materials. We experimentally investigate and model THz spintronic emission based on the spin Hall effect in 3d/5d transition metals and on the inverse Rashba-Edelstein effect in the optimized topological insulator Bi1-xSbx.
