Connectivity-Dependent Exciton-Phonon Coupling in Cesium Bismuth Halide Quantum Dots.

Metal halide octahedra form the fundamental functional building blocks of metal halide perovskites, dictating their structures, optical properties, electronic structures, and dynamics. In this study, we show that the connectivity of bismuth halide octahedra in CsBiBr and CsBiI quantum dots (QDs) changes with different halide elements. We use first-principles calculations to reveal the key role of the connectivity of bismuth halide octahedra on the wave function symmetry, Huang-Rhys factor, and exciton-phonon interaction strength.

State- and territory-based differences that impede the establishment of a harmonised national registry.

ObjectiveThis paper aims to identify and describe legislative and administrative barriers to hospital participation and national data linkage for the National Australian Congenital Heart Disease (CHD) Registry.MethodsA narrative review based on the National Australian CHD Registry experience of establishing participating hospital sites and national linkages associated with each jurisdiction.ResultsThere were numerous identified barriers that could be overcome with additional resources/time, and barriers that could not be overcome, reported by jurisdiction.
