WebMultiphonon Raman scattering with up to fourth-order longitudinal optical (LO) overtones is observed under above-band gap excitation, indicating a strong electron-phonon coupling (EPC) that could be described by the cascade model. The Huang-Rhys factor was derived to characterize the strength of EPC and was found to be increasing with ... WebApr 3, 2024 · One proposed mechanism is the electron-phonon coupling, where electrons in a material interact with the vibrations of the crystal lattice, leading to a net attraction between the electrons and the ...

WebJan 19, 2024 · Phonon–phonon and electron/exciton–phonon coupling play a vitally important role in thermal, electronic, as well as optical properties of metal halide perovskites. In this work, we evaluate phonon anharmonicity and coupling between electronic and vibrational excitations in novel double perovskite Cs2NaFeCl6 single crystals. By … WebAug 16, 2024 · The electron–phonon coupling constant ( λ ≃ 0.80) indicates that Ti 3 Sb has strong electron–phonon coupling. The critical temperature ( T c μ ⋆ = 0.10) is found to be 6.24 and 6.56 K with and without the SOC effect, respectively. Due to Ti’s relatively small SOC strength, we do not find evidence of non-trivial topology in contrast ... how much to pay for sirius xm
