Time-dependent terahertz dielectric function of ZnTe under two-photon optical excitation at 800 nm wavelength
Farell Keiser, Wentao Zhang, Dominik Johannesmann +5
ZnTe is arguably the most widely used nonlinear crystal for the generation and detection of THz radiation, used in conjunction with sub-bandgap optical excitation by femtosecond la…
Enhanced THz emission from spintronic emitters with Pt-Al alloys
Felix Janus, Nicolas Beermann, Jyoti Yadav +5
Platinum (Pt) is the element with the largest spin Hall conductivity and is known as the most efficient spin-to-charge conversion material in spintronic THz emitters. By alloying w…
Emergent spin Hall conductivity in Tantalum-Rhenium alloys
Felix Janus, Jyoti Yadav, Nicolas Beermann +5
We investigate the spin Hall conductivity (SHC) of a composition series of a Ta-Re bcc solid solution. At approximately 60 at.% Ta the Ta-Re alloy features an SHC similar to bcc-W,…
Efficient Spintronic THz Emitters Without External Magnetic Field
Amir Khan, Nicolas Sylvester Beermann, Shalini Sharma +4
We investigate the performance of state-of-the-art spintronic THz emitters (W or Ta)/CoFeB/Pt with non-magnetic underlayer deposited using oblique angle deposition. The THz emissio…
Disentangling complex current pathways in a metallic Ru/Co bilayer nanostructure using THz spectroscopy
Nicolas S. Beermann, Savio Fabretti, Karsten Rott +3
Many modern spintronic technologies, such as spin valves, spin Hall applications, and spintronic THz emitters, are based on electrons crossing buried internal interfaces within met…
