How Exciton Interactions Control Spin-Depolarization in Layered Hybrid Perovskites

Bourelle, S.A.; Shivanna, R.; Camargo, F.V.A.; Ghosh, S.; Gillett, A.J.; Senanayak, S.P.; Feldmann, S.; Eyre, L.; Ashoka, A.; van de Goor, T.W.J.; Abolins, H.; Winkler, T.; Cerullo, G.; Friend, R.H.; Deschler, F. (Nano Letters, 20(8), 2020: 5678-5685)

Using circularly polarized broadband transient absorption, time-resolved circular photoluminescence, and transient Faraday rotation spectroscopy, we report that spin-dependent interactions have a significant impact on ...
Photodoping through local charge carrier accumulation in alloyed hybrid perovskites for highly efficient luminescence

Feldmann, S.; Macpherson, S.; Senanayak, S.P.; Abdi-Jalebi, M.; Rivett, J.P.H.; Nan, G.J.; Tainter, G.D.; Doherty, T.A.S.; Frohna, K.; Ringe, E.; Friend, R.H.; Sirringhaus, H.; Saliba, M.; Beljonne, D.; Stranks, S.D.; Deschler, F. (Nature Photonics, 14(2), 2020: 123-+)

Localized photodoping in mixed-cation perovskites is shown to modify charge-carrier recombination and thus offer a route for more efficient light emission. Metal halide perovskites have emerged as exceptional semiconductors ...
