Shaping THz emission spectra by using sub-wavelength nanopatterned spintronic THz emitters
Bikash Das-Mohapatra, Reza Rouzegar, Evangelos Th. Papaioannou +2
We show in theory and experiment that in periodically patterned spintronic THz emitters (STE), charge dynamics can modify the emission spectrum in a well-controlled way. Characteri…

Charge dynamics in spintronic THz emitters
Georg Schmidt, Bikash Das-Mohapatra, Evangelos Th. Papaioannou
We show that to correctly describe the ultrafast currents in spintronic THz emitters it is necessary to take charge equilibration into account. The charge current which is locally…
