Ultrafast acoustic phonon scattering in CHNHPbI revealed by femtosecond four-wave mixing
Samuel A. March, Drew B. Riley, Charlotte Clegg +4
Carrier scattering processes are studied in CHNHPbI using temperature-dependent four-wave mixing experiments. Our results indicate that scattering by ionized impurities…
Controlling magnetoresistance by oxygen impurities in Mq3-based molecular spin valves
Alberto Riminucci, Zhi-Gang Yu, Mirko Prezioso +4
The understanding of magnetoresistance (MR) in organic spin valves (OSVs) based on molecular semiconductors is still incomplete after its demonstration more than a decade ago. Whil…
Detection of Rashba spin splitting in 2D organic-inorganic perovskite via precessional carrier spin relaxation
Seth B. Todd, Drew B. Riley, Ali Binai-Motlagh +8
The strong spin-orbit interaction in the organic-inorganic perovskites tied to the incorporation of heavy elements (\textit{e.g.} Pb, I) makes these materials interesting for appli…
Metasurface polarization splitter
Brian A. Slovick, You Zhou, Zhi Gang Yu +5
Polarization beam splitters, devices that separate the two orthogonal polarizations of light into different propagation directions, are one of the most ubiquitous optical elements.…
Generalized effective-medium theory for metamaterials
Brian A. Slovick, Zhi Gang Yu, Srini Krishnamurthy
We present an effective-medium model for calculating the frequency-dependent effective permittivity and permeability of metamaterial composites containing spherical p…
Spin Gunn Effect
Yunong Qi, Zhi-Gang Yu, Michael E. Flatté
We predict that the flow of unpolarized current in electron-doped GaAs and InP at room temperature is unstable at high electric fields to the dynamic formation of spin-polarized cu…
