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…
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…
Carrier Diffusion in Thin-Film CH3NH3PbI3 Perovskite Measured using Four-Wave Mixing
D. Webber, C. Clegg, A. W. Mason +3
We report the application of femtosecond four-wave mixing (FWM) to the study of carrier transport in solution-processed CH3NH3PbI3. The diffusion coefficient was extracted through…
Four-wave mixing in perovskite photovoltaic materials reveals long dephasing times and weaker many-body interactions than GaAs
Samuel A. March, Drew B. Riley, Charlotte Clegg +6
Perovksite semiconductors have shown promise for low-cost solar cells, lasers and photodetectors, yet their fundamental photophysical properties are not well understood. Recent obs…
Non-magnetic semiconductor spin transistor
K. C. Hall, Wayne H. Lau, K. Gundogdu +2
We propose a spin transistor using only non-magnetic materials that exploits the characteristics of bulk inversion asymmetry (BIA) in (110) symmetric quantum wells. We show that ex…
