Giant Electron-Phonon Coupling Induced Band-Gap Renormalization in Anharmonic Silver Chalcohalide Antiperovskites
Pol Benítez, Siyu Chen, Ruoshi Jiang +6
Silver chalcohalide antiperovskites (CAP), AgXY (X = S, Se; Y = Br, I), are a family of highly anharmonic inorganic compounds with great potential for energy applications. Ho…
Characterization of Spin-Orbit Effects in Superconductors InBi and InSb
Yao Wei, Siyu Chen, Bartomeu Monserrat
We report a first principles computational analysis of two phonon-mediated superconductors, InBi and InSb. We show that spin-orbit coupling leads to splitti…
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…
Origin of competing charge density waves in kagome metal ScVSn
Kang Wang, Siyu Chen, Sun-Woo Kim +1
Understanding competing charge density wave (CDW) orders in the bilayer kagome metal ScVSn remains challenging. Experimentally, upon cooling, short-range order with wave ve…
Lattice dynamics of quasi-2D perovskites from first-principles
Emily Y. Chen, Bartomeu Monserrat
We present the vibrational properties and phonon dispersion for quasi-2D hybrid organic-inorganic perovskites (BA)CsPbI, (HA)CsPbI, (BA)(MA)PbI,…
