(c): Fourier transform of the data in (b) showing the spectral content of the radiation. This signal is significantly larger for samples with a Ag/Bi bilayer compared to control samples with individual layers. (Image by Argonne National Laboratory.)
THz-radiation generated from interfacial spin-orbit coupling

In a recent study published by Physical Review Letters, researchers in Argonne’s Materials Science division and at the Center for Nanoscale Materials, a U.S. Department of Energy Office of Science User Facility, demonstrate that interfacial spin-orbit coupling and ultrafast spin-charge current transfer can generate THz radiation.

Depiction of the peptide amphiphile, PA (A) and the zinc porphyrin, ZnP (B, shown as both sticks and spheres) that comprise the doped nanofibers. Sheets are shown for high doping ratios of ZnP:PA (C,E,G) and low doping ratios (D,F,H). C and D highlight the relative ZnP packing and E and F illustrate the variation in ZnP spacing. G and H highlight the fiber cross sections.
