(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.

Researchers from Argonne National Laboratory developed a first-principles-based, variable-charge force field that has shown to accurately predict bulk and nanoscale structural and thermodynamic properties of IrO2. Catalytic properties pertaining to the oxygen reduction reaction, which drives water-splitting for the production of hydrogen fuel, were found to depend on the coordination and charge transfer at the IrO2 nanocluster surface.
