Chalcogenide perovskites have garnered interest for applications in semiconductor devices due to their excellent predicted optoelectronic properties and stability. However, high synthesis temperatures historically made these materials incompatible with the creation of photovoltaic devices. Here, we demonstrate solution processed luminescent BaZrS3 BaHfS3 chalcogenide perovskite films using single-phase molecular precursors at sulfurization 575 °C times as short one hour. These precursor inks...
Abstract Chalcogenide perovskites have garnered increasing attention as stable, non‐toxic alternatives to lead halide perovskites. However, their conventional synthesis at high temperatures (>1000 °C) has hindered widespread adoption. Recent studies developed low‐to‐moderate temperature methods (<600 using reactive precursors, yet a comprehensive understanding of the pivotal factors affecting reproducibility and repeatability remains elusive. This study delineates critical in...
Topologically interlocked material systems are two-dimensional granular crystals created as ordered and adhesion-less assemblies of unit elements the shape platonic solids. The assembly resists transverse forces due to interlocking geometric arrangement elements. yet require an external constraint provide resistance under action load. Past work considered fixed passive constraints only. objective present study is consider active adaptive with goal achieve variable stiffness energy absorption...
Topologically interlocked materials (TIMs) are a class of 2D mechanical crystals made by structured assembly an array polyhedral elements. The monolayer can resist transverse forces in the absence adhesive interaction between unit properties system emerge as combination deformation individual elements and their contact interaction. present study presents scaling laws relating stiffness monolayered TIMs to characteristic dimensions. concept thrust line analysis is employed obtain laws, model...

The enargite phase of Cu3AsS4 (ENG) is an emerging photovoltaic material with a ∼1.4 eV bandgap and composed earth abundant elements favorable defect properties arising from the differing ionic radii constituent elements. Unfortunately, ENG-based devices have experimentally been shown to low power conversion efficiencies, possibly due defects in material. In this joint computational experimental study, we explore ENG employ synthesis approaches, such as silver alloying, reduce density...
