Abstract: Abstract We report a study of the electron–phonon contribution to the linewidth of quantum-well states in a surface superstructure formed by a 4/3-monolayer of Pb on Si(111), a dense phase with a 3 × 3… read more here.

DOI: 10.1039/c7tc04695b
Abstract: In this study, a series of (KxNa1−x)2SiF6:Mn4+ red phosphors with systematic composition variations of alkali metals was synthesized via a low-temperature full-solution approach. Driven by composition variations, a sequence of continuous structural phase transformations, i.e.,… read more here.

Abstract: It is well known that phonon-induced relaxation processes play a significant role in accelerating magnetization relaxation in the low-temperature regime. Unfortunately, many SIMs (single-ion magnets) suffer from being quenched by these mechanisms such that neither… read more here.

DOI: 10.1103/physrevb.101.045402
Abstract: We present an effective low-energy theory of electron-phonon coupling effects for clean cylindrical topological insulator nanowires. Acoustic phonons are modelled by isotropic elastic continuum theory with stress-free boundary conditions. We take into account the deformation… read more here.

DOI: 10.1103/physrevlett.129.076402
Abstract: Ab initio calculations of the phonon-induced band structure renormalization are currently based on the perturbative Allen-Heine theory and its many-body generalizations. These approaches are unsuitable to describe materials where electrons form localized polarons. Here, we develop… read more here.

DOI: 10.1103/physrevlett.130.086401
Abstract: The spatial extent of excitons in molecular systems underpins their photophysics and utility for optoelectronic applications. Phonons are reported to lead to both exciton localization and delocalization. However, a microscopic understanding of phonon-induced (de)localization is… read more here.
