Increasing the Efficiency of a Spintronic THz Emitter Based on WSe2/FeCo

We report an increase in terahertz (THz) radiation efficiency due to FeCo/WSe2 structures in the reflection geometry. This can be attributed to an absorption increase in the alloy FeCo layer at the input FeCo/WSe2 interface due to constructive interferen...
