Local Symmetry Breaking Drives Picosecond Spin Domain Formation in Polycrystalline Semiconducting Films
Arjun Ashoka, Satyawan Nagane, Nives Strkalj +6
Photoinduced spin-charge interconversion in semiconductors with spin-orbit coupling could provide a route to optically addressable spintronics without the use of external magnetic…
The critical role of the donor polymer in the stability of high-performance non-fullerene acceptor organic solar cells
Yiwen Wang, Alberto Privitera, Giacomo Londi +7
Driven by the rapid development of non-fullerene electron acceptors (NFAs), the power conversion efficiencies of organic solar cells (OSCs) have reached levels suitable for commerc…
Dielectric control of reverse intersystem crossing in thermally-activated delayed fluorescence emitters
Alexander J. Gillett, Anton Pershin, Raj Pandya +12
Thermally-activated delayed fluorescence (TADF) enables organic semiconductors with charge transfer (CT)-type excitons to convert dark triplet states into bright singlets via a rev…
Direct Observation of Ultrafast Singlet Exciton Fission in Three Dimensions
Arjun Ashoka, Nicolas Gauriot, Aswathy V. Girija +7
We present quantitative ultrafast interferometric pump-probe microscopy capable of tracking of photoexcitations with sub 10 nm spatial precision in three dimensions with 15 fs temp…
Efficient Energy Transport in an Organic Semiconductor Mediated by Transient Exciton Delocalization
Alexander J. Sneyd, Tomoya Fukui, David Palecek +15
Efficient energy transport is highly desirable for organic semiconductor (OSC) devices such as photovoltaics, photodetectors, and photocatalytic systems. However, photo-generated e…
Spherical topological-insulator nanoparticles: Quantum size effects and optical transitions
L. Gioia, M. G. Christie, U. Zülicke +2
We have investigated the interplay between band inversion and size quantization in spherically shaped nanoparticles made from topological-insulator (TI) materials. A general theore…
