Summary: This study investigated the performance enhancement mechanism of the device after surface reconstruction by passivating different halogen groups at the ETL/perovskite interface using density functional theory combined with ab initio molecular dynamics. Halogen passivation stabilized the geometric structure of the perovskite surface, optimized surface reconstruction, and theoretically relieved the interface carrier recombination by balancing interfacial interaction. The findings have implications for the design of buried interface optimization in perovskite optoelectronic devices.

Summary: Blending semiconductors is a cost-effective method for developing new materials with attractive features, where the final properties of the blend depend on the materials' proportions and mixability. By characterizing a ternary blend of Pentacene, MoS2, and ZnO, it was found that different proportions of the blend lead to varied structural and optical properties. The performance of optoelectronic devices is highly influenced by the composition sensitivity of the blend, indicating the potential for blended materials in dynamic optoelectronic device applications.

Summary: Engineering semiconductor materials with vacancies and co-catalysts is an effective method to enhance their photocatalytic performance. In this study, Mn0.3Cd0.7S nanorods modified with S vacancies and ?-Ni(OH)2 nanoparticles exhibited excellent visible-light H2-production activity, attributed to enhanced transfer/separation of photogenerated carriers and increased reaction sites. These findings propose a new approach for utilizing metal hydroxide co-catalysts and vacancies in sulfide materials for photocatalytic H2 production.

Summary: The development of new n-type semiconductors with tunable band gap and dielectric constant is important for high-performance optoelectronic devices. Boron-beta-thioketonates (MTDKB), which are analogues to boron-beta-diketonates containing a sulfur atom, were synthesized. The MTDKBs exhibited outstanding bulk electron mobility and single junction photo responsivity. They also showed luminescent properties and were investigated as fluorescent sensors with amine functionality.

Summary: A novel ternary nanocomposite of Ag@RGO/ZnO was successfully synthesized using a facile one-pot method at room temperature, which functions as a low-cost, efficient, and reliable UV absorber. The optical characterization showed enhanced light absorption in the UV portion, attributed to the synergetic effect of Ag nanoparticles and RGO nanosheets. Additionally, the band-gap narrowing due to Ag-doping suggests potential applications for this nanocomposite.

Summary: The growth of low-dimensional zinc oxide (ZnO) nanostructures, such as nanorods and nanoflowers, can be kinetically controlled by adjusting the hydroxide ion concentration in the precursor, resulting in enhanced photoluminescent emission. The concentration of hydroxide ions in the precursor influences the aspect ratio of the nanostructures and morphology of the samples, affecting the photoluminescent emission. The formation of superoxide charge transfer states due to adsorption of oxygen at grain boundaries or induced by hydroxide ions plays a significant role in enhancing the efficiency of ZnO-based optoelectronic devices.

Summary: Plasmonics, particularly localized surface plasmon resonance (LSPR) in non-noble metal bismuth nanoparticles (Bi NPs), and their spectral properties have garnered research interest. The study successfully synthesized size-tunable spherical Bi NPs through a thiolate pyrolysis reaction, allowing for precise control of diameters ranging from 65 to 205 nm. The size-dependent LSPR optical properties of Bi NPs showed rich UV-visible-near-infrared spectral responses, with complete oxidation leading to the formation of metastable tetragonal-phase beta-Bi2O3 NPs and interesting polymorphic transitions.

Summary: Etching anisotropy is a common phenomenon used in chemical etching to create micro/nanostructures with specific shapes and properties. In this study, we demonstrate the anisotropy in wet etching of 2D tin monosulfide microflakes. The use of a thiol-amine mixture solvent as the etchant enables the preferential etching of specific surfaces and vertices of the microflakes, resulting in the transformation of their shape. This work opens up possibilities for tailoring the size, shape, and crystal surface of inorganic-nonmetallic chalcogenides using etching chemistry.
