Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
Photo-induced plasmon-phonon coupling in PbTe
M. P. Jiang, M. Trigo, S. Fahy +19
We report the observation of photo-induced plasmon-phonon coupled modes in the group IV-VI semiconductor PbTe using Fourier-transform inelastic X-ray scattering at the Linac Cohere…
INQ, a modern GPU-accelerated computational framework for (time-dependent) density functional theory
Xavier Andrade, Chaitanya Das Pemmaraju, Alexey Kartsev +6
We present INQ, a new implementation of density functional theory (DFT) and time-dependent DFT (TDDFT) written from scratch to work on graphical processing units (GPUs). Besides GP…
Universal phase dynamics in VO2 switches revealed by ultrafast operando diffraction
Aditya Sood, Xiaozhe Shen, Yin Shi +9
Strongly correlated materials that exhibit an insulator-metal transition are key candidates in the search for new computing platforms. Understanding the pathways and timescales und…
Electrochemical Ion Insertion: From Atoms to Devices
Aditya Sood, Andrey D. Poletayev, Daniel A. Cogswell +7
Electrochemical ion insertion involves coupled ion-electron transfer reactions, transport of guest species, and redox of the host. The hosts are typically anisotropic solids with t…
Visualization of Dynamic Polaronic Strain Fields in Hybrid Lead Halide Perovskites
B. Guzelturk, T. Winkler, T. Van de Goor +14
Excitation localization involving dynamic nanoscale distortions is a central aspect of photocatalysis, quantum materials and molecular optoelectronics. Experimental characterizatio…
