Identifying Hidden Intracell Symmetries in Molecular Crystals and their Impact for Multiexciton Generation
Aaron R. Altman, Sivan Refaely-Abramson, Felipe H. da Jornada
Organic molecular crystals are appealing for next-generation optoelectronic applications, most notably due to their multiexciton generation process that can increase the efficiency…
Theory of Chirality Induced Spin Selectivity: Progress and Challenges
Ferdinand Evers, Amnon Aharony, Nir Bar-Gill +19
We provide a critical overview of the theory of the chirality-induced spin selectivity (CISS) effect, i.e., phenomena in which the chirality of molecular species imparts significan…
Signatures of Dimensionality and Symmetry in Exciton Bandstructure: Consequences for Time-Evolution
Diana Y. Qiu, Galit Cohen, Dana Novichkova +1
Exciton dynamics, lifetimes and scattering are directly related to the exciton dispersion, or bandstructure. While electron and phonon bandstructures are well understood and can be…
Layer-dependent Quasiparticle Electronic Structure of the P3HT:PCBM Interface from A First-Principles Substrate Screening Approach
Olugbenga Adeniran, Sivan Refaely-Abramson, Zhen-Fei Liu
A prototypical organic photovoltaic material is a heterojunction composed of the blend of regioregular poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C-butyric acid methyl e…
Quantum phase transitions of tri-layer excitons in atomically thin heterostructures
Yevgeny Slobodkin, Yotam Mazuz-Harpaz, Sivan Refaely-Abramson +3
We determine the zero temeperature phase diagram of excitons in the symmetric transition-metal dichalcogenide tri-layer heterosctructure WSe2/MoSe2/WSe2. First principle calculatio…
Large spin-orbit splitting of deep in-gap defect states of engineered sulfur vacancies in monolayer WS2
Bruno Schuler, Diana Y. Qiu, Sivan Refaely-Abramson +10
Structural defects in 2D materials offer an effective way to engineer new material functionalities beyond conventional doping in semiconductors. Specifically, deep in-gap defect st…
