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…
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…
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…
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…
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…
