A hidden bulk polymorph governs charge transport dimensionality in an organic semiconductor
Caterina Zuffa, Marco Bardini, Fabian Gasser +11
Organic semiconductors (OSCs) are widely explored for flexible optoelectronic technologies, with performance governed not only by molecular design, but also by solid-state packing,…
Generalized thermodynamic closure in ultrafast phonon dynamics
Sheng Qu, Jiyong Kim, Jaco J. Geuchies +9
Driven-dissipative dynamics underlie a wide range of nonequilibrium phenomena in quantum materials, yet reduced descriptions beyond the quasi-equilibrium picture remain difficult t…
Temperature- and charge carrier density-dependent electronic response in methylammonium lead iodide
Jiacheng Wang Jungmin Park, Lei Gao, Lucia Di Virgilio +8
Understanding carrier dynamics in photoexcited metal-halide perovskites is key for optoelectronic devices such as solar cells (low carrier densities) and lasers (high carrier densi…
Anisotropic electron-phonon interactions in 2D lead-halide perovskites
Jaco J. Geuchies, Johan Klarbring, Lucia Di Virgillio +8
Two-dimensional hybrid organic-inorganic metal halide perovskites offer enhanced stability for perovskite-based applications. Their crystal structure's soft and ionic nature gives…
Identifying the Origin of Thermal Modulation of Exchange Bias in MnPS3/Fe3GeTe2 van der Waals Heterostructures
Aravind Puthirath Balan, Aditya Kumar, Patrick Reiser +21
The exchange bias phenomenon, inherent in exchange-coupled ferromagnetic and antiferromagnetic systems, has intrigued researchers for decades. Van der Waals materials, with their l…
Signatures of Mode-Resolved, Nonlocal Electron-Phonon Coupling in Two-Dimensional Spectroscopy
Sheng Qu, Vishal K. Sharma, Jaco Geuchies +4
Electron-phonon coupling (EPC) is foundational in condensed matter physics, determining intriguing phenomena and properties in both conventional and quantum materials. In this manu…
Controlling the electro-optic response of a semiconducting perovskite coupled to a phonon-resonant cavity
Lucia Di Virgilio, Jaco J. Geuchies, Heejae Kim +4
Optical cavities, resonant with vibrational or electronic transitions of material within the cavity, enable control of light-matter interaction. Previous studies have reported cavi…
Transiently delocalized states enhance hole mobility in organic molecular semiconductors
Samuele Giannini, Lucia Di Virgilio, Marco Bardini +13
There is compelling evidence that charge carriers in organic semiconductors (OSs) self-localize in nano-scale space because of dynamic disorder. Yet, some OSs, in particular recent…
Zero-threshold optical gain in electrochemically doped nanoplatelets and the physics behind it
Jaco J. Geuchies, Robbert Dijkhuizen, Marijn Koel +5
Colloidal nanoplatelets (NPLs) are promising materials for lasing applications. The properties are usually discussed in the framework of 2D materials, where strong excitonic effect…
Quantitative electrochemical control over optical gain in quantum-dot solids
Jaco J. Geuchies, Baldur Brynjarsson, Gianluca Grimaldi +4
Realizing solution processed quantum dot (QD) lasers is one of the holy-grails of nanoscience. The reason that QD lasers are not yet commercialized is that the lasing threshold is…
