Mechanical failure and chemical degradation of device heterointerfaces can strongly influence the long-term stability perovskite solar cells (PSCs) under thermal cycling damp heat conditions. We report chirality-mediated interfaces based on
Optomechanical reliability has emerged as an important criterion for evaluating the performance and commercialization potential of perovskite solar cells (PSCs) due to mechanical-property mismatch metal halide perovskites with other device layer. In this work, grain-boundary grooves, a rarely discussed film microstructural characteristic, are found impart significant effects on optomechanical perovskite-substrate heterointerfaces thus PSC performance. By pre-burying iso-butylammonium...

With varied concentration co-doped europium and terbium in 1,3,5-benzenetricarboxylate, the emitting colors obtained materials changed under same excitation wavelength.
We report an on-chip light-incorporated in situ transmission electron microscopy (LI2ST) approach for probing metal halide perovskites (MHPs) at the nanoscale, realizing real-time, site-specific tracking of light-triggered structure transformation. This platform is based on a specifically designed microelectromechanical systems (MEMS) chip that offers capability light illumination with adjustable intensity and tailorable multiwavelength. The excellent operational reliability allows...
Abstract Achieving strong and broadband circularly polarized colour responses in chiral inorganic materials is challenging. Here, we fabricated mesostructured bismuth oxybromide (BiOBr) films (CMBFs) via hydrothermal growth using sugar alcohols as symmetry‐breaking agents. The layered slabs of BiOBr crystals with weak van‐der‐Waals interactions are prone to mismatching due the driving force, resulting hierarchically arrangements fine size. Three levels chirality exist CMBFs: primary, helical...

Abstract Chirality is an attribute based on the structural geometry of materials, which confers a distinctive energy band structure for intriguing optical, electronic, and spintronic properties. Recent studies chirality encountered in perovskite(‐inspired) halides (PiHs) have drawn increasing attention, not only because large chemical diversity PiHs seen at molecular, nanoscopic, microscopic levels, but also due to observation various emergent properties multifunctional device applications....
The bigger pictureThe fast-paced advancements in artificial intelligence (AI) and the internet of things (IoT) necessitate highly efficient edge computing. A crucial component this scenario is memristor, a specialized sensor adept at processing information within memory. This technology essential for swift decision-making, optimized data utilization, reduced energy consumption. However, there need innovative materials memristors. In context, metal halide perovskites possess unique properties...
Chiral superstructures are ubiquitous in nature and display intriguing elegant performances, which inspired us to realize multiscale chiral mesostructured inorganics. Here, we report cholic acid-induced anisotropic epitaxial growth of CdSe/CdS nanorods (CCCNs) their self-assembly into nematic-like films (CNFs) via an evaporation-induced route. Three levels chirality exist the CNFs assembled with CCCNs: a primary distortion nanorod, secondary phase layered nanobelts stacked form side-by-side...
Abstract Organic–inorganic halide perovskites (OIHPs) show high promise in optical and electronic applications such as solar cells, light‐emitting diodes, nonlinear optics. However, the fundamental knowledge of atomic‐scale microstructures OIHP thin films is limited due to challenge characterizing them using transmission electron microscopy (TEM). Here a solution‐phase “release‐and‐transfer” method demonstrated, which entails lifting from their original substrates while maintaining film...

The enantiomeric excess phenomenon in spontaneous chiral symmetry breaking (SCSB) is a crucial issue regarding the origin of homochirality prebiotic environment . Although formation inorganic compounds with space groups and lattice dislocations has been extensively investigated, rarely considered, convention being to assume presence racemic mixture. Here, we report SCSB self-assembly cadmium chalcogenide nanorods, leading biases away from racemate. In achiral organics, helical CdSe@CdS...
