Engineering surface structure can precisely and effectively tune the optoelectronic properties of halide perovskites, but are incredibly challenging. Herein, design fabrication uniform all-inorganic CsPbBr3 cubic/tetrahedral single-crystals reported with precise control (100) (111) anisotropy, respectively. By combining theoretical calculations, it is demonstrated that preferred engineering enables a lowest bandgap energy (2.33 eV) high-rate carrier mobility up to 241 μm2 V-1 s-1 ,...
Large-sized, high-quality square CsPb 2 Br 5 sheets were synthesized via a solution-based method, exhibiting excellent performance for use in photodetectors.
Abstract Ion diffusion is a fundamentally important process in understanding and manipulating the optoelectronic properties of semiconductors. Most current studies on ionic have been focusing perovskite polycrystalline thin films nanocrystals. However, random orientation grain boundaries can heavily interfere with kinetics ion diffusion, where experimental results only reveal average exchange actual mechanisms perpendicular to direction individual crystal facets remain unclear. Here, anion...
Abstract 0D/3D perovskite heterostructures have been extensively utilized in optoelectronic devices. However, synthesizing with well‐defined interfaces, high‐exposure crystal facet orientations, and high‐purity phases remains challenging due to their soft ionic nature, which complicates the understanding of ion defect passivation mechanisms these heterostructure systems. In this study, a one‐step vapor‐phase epitaxial growth pure‐phase single‐crystal is reported interfaces. Through...

Single-crystalline Sb 2 S 3 rods were successfully used to fabricate high-performance photodetector after surface cleaning and defect suppression through post-annealing in H /Ar atmosphere.
Formamidinium lead triiodide (FAPbI3) perovskite has received great attention because of its distinct optoelectronic property, smaller band gap (~1.5 eV), and higher thermal stability than methylammonium (MAPbI3). However, the efficient synthesis such materials on a large scale at low cost remains challenge. In this work, mixed-cation FA1−xCsxPbI3 thin films were directly prepared in an atmospheric environment with high film formation rate, material loss, cost, requirements for experimental...
Narrowing the band gap and increasing photodegradation efficiency of TiO2-based photocatalysts are very important for their wide application in environment-related fields such as photocatalytic degradation toxic pollutants wastewater. Herein, a three-dimensionally ordered macroporous Pt-loaded TiO2 photocatalyst (3DOM Pt/TiO2) has been successfully synthesized using facile colloidal crystal-template method. The resultant composite combines several morphological/structural advantages,...
