Chern junctions in Moiré-Patterned Graphene/PbI2
Sun Yan, M. Monteverde, V. Derkach +5
Expanding the moire material library continues to unlock novel quantum phases and emergent electronic behaviors. Here, we introduce PbI2 into the moire family and investigate the m…
Spin dependent fluorescence mediated by anti-symmetric exchange in triplet exciton pairs
Yan Sun, M. Monteverde, V. Derkach +4
Singlet fission and triplet-triplet annihilation (TTA) are spin-dependent phenomena critical to optoelectronics. The dynamics of spin populations during geminate triplet pair separ…
Cascade of multi-exciton states generated by singlet fission
Yan Sun, M. Monteverde, V. Derkach +2
Identifying multi-exciton states generated from singlet fission is key to understanding the carrier multiplication process, which presents a strategy for improving the efficiency o…
Optical read and write of spin states in organic diradicals
Rituparno Chowdhury, Petri Murto, Naitik A. Panjwani +17
Optical control and read-out of the ground state spin structure has been demonstrated for defect states in crystalline semiconductors, including the diamond NV- center, and these a…
Quantum Transport and Spectroscopy of Two-dimensional Perovskite/Graphene Interfaces
Yan Sun, C. Morice, D. Garrot +5
Quantum transport properties in molecularly thin perovskite/graphene heterostructure are experimentally investigated by Shubnikov-de Hass (SdH) oscillation and photo-resistance spe…
