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…
Panoramic mapping of phonon transport from ultrafast electron diffraction and machine learning
Zhantao Chen, Xiaozhe Shen, Nina Andrejevic +11
One central challenge in understanding phonon thermal transport is a lack of experimental tools to investigate mode-based transport information. Although recent advances in computa…
Role of equilibrium fluctuations in light-induced order
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +17
Engineering novel states of matter with light is at the forefront of materials research. An intensely studied direction is to realize broken-symmetry phases that are "hidden" under…
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…
Ultrafast formation of transient 2D diamond-like structure in twisted bilayer graphene
Duan Luo, Dandan Hui, Bin Wen +17
Due to the absence of matching carbon atoms at honeycomb centers with carbon atoms in adjacent graphene sheets, theorists predicted that a sliding process is needed to form AA, AB,…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
