2 giorni fa · Symmetry breaking is prevalent in nature and provides distinctive access to hierarchical structures for artificial materials. However, it is rarely explored in two-dimensional (2D) entities, especially for lateral asymmetry. Herein, we describe a unique symmetry breaking process in surface-initiated 2D living crystallization-driven self-assembly. The 2D epitaxial growth occurs only at one ...
2 giorni fa · Our analysis shows that the incorporation of σ-side groups induces symmetry breaking in the frontier orbitals and increases intramolecular scattering, which then leads to reduced conductance. Conversely, the integration of π-side groups augments the molecular conductance through the multiple-channel effect, by which an additional π pathway is introduced for charge transport.
7 mag 2024 · The eleven papers collected in this Special Issue are indeed diverse: in two or three dimensions, fundamental and applied, at macro and micro scales, elucidating flows that are symmetric, symmetry-breaking, and intermittently symmetric, and in uniform and stratified fluids. The phenomena addressed include single-drop dynamics, hydrodynamic ...
1 giorno fa · The R-stacked configuration is achieved by the symmetry breaking in a-plane sapphire, where the influence of atomic steps passes through the lower TMD layer and controls the R-stacking of the ...
21 apr 2024 · Abstract. Nature-inspired supramolecular self-assemblies are attractive photocatalysts, but their quantum yields are limited by poor charge separation and transportation. A promising strategy for efficient charge transfer is to enhance the built-in electric field by symmetry breaking.
25 apr 2024 · Symmetry Breaking and Spatiotemporal Pattern Formation in Photonic Time Crystals. Egor I. Kiselev, Yiming Pan. In this work, we explore the dynamics of time varying photonic media with an optical Kerr nonlinearity and an associated phase transition.
