Enhancement of exciton radius near a band-gap closing through quantum geometry
Jin-Hyung Choi, Sang-Hoon Han, Young-Kwon Han +3
Exciton engineering traditionally focuses on modifying semiclassical material properties, such as the effective mass and dielectric screening, while largely overlooking the quantum…
Generalized Shift Vector as the Intrinsic Dipole of Many-Body Correlated Electronic States
Jiaming Hu, Sudipta Kundu, Zhichao Guo +4
Shift vectors play a central role in nonlinear optics and transport phenomena, where they are usually understood as charge-center shifts associated with transitions between quantum…
Ultrafast anisotropic exciton transport in phosphorene
Kai-Wei Chang, Joshua J. P. Thompson, Bartomeu Monserrat
Phosphorene is a two-dimensional (2D) material exhibiting strong in-plane structural anisotropy. In this work, we investigate the influence of structural anisotropy on the optics,…
Steric Engineering of Exciton Fine Structure in 2D Perovskites
Mateusz Dyksik, Michal Baranowski, Joshua J. P. Thompson +5
A comprehensive study of excitonic properties of 2D layered perovskites is provided, with an emphasis on understanding and controlling the exciton fine structure. First, an overvie…
Topologically-enhanced exciton transport
Joshua J. P. Thompson, Wojciech J. Jankowski, Robert-Jan Slager +1
Excitons dominate the optoelectronic response of many materials. Depending on the time scale and host material, excitons can exhibit free diffusion, phonon-limited diffusion, or po…
Circularly polarised electroluminescence from chiral excitons in vacuum-sublimed supramolecular semiconductor thin films
Rituparno Chowdhury, Marco D. Preuss, Hwan-Hee Cho +21
Materials with chiral electronic structures are of great interest. We report a triazatruxene, TAT, molecular semiconductor with chiral alkyl side chains that crystallises from solu…
Excitonic topology and quantum geometry in organic semiconductors
Wojciech J. Jankowski, Joshua J. P. Thompson, Bartomeu Monserrat +1
Excitons drive the optoelectronic properties of organic semiconductors which underpin devices including solar cells and light-emitting diodes. Here we show that excitons can exhibi…
