Summary: In this study, the effects of polyethylene glycol (PEG) and L-3,4-dihydroxyphenylalanine (L-dopa) as structure directing agents on the growth of tungsten trioxide crystals by solvothermal method in acetonitrile solution were investigated. The presence of PEG and L-dopa led to a change in crystal growth mechanism, resulting in the transformation of crystal faces from stacked layers to smooth facets. The rate of crystal formation and growth was significantly increased in the presence of 5 w% PEG. The crystals grown in the presence of L-dopa were octahedral WO3·0.5H2O with smooth faces, while those grown in the presence of PEG were octahedral and rectangular microcrystals of WO3·H2O. The transparency and electro-optical properties of the crystal layers were improved in the presence of PEG.

Summary: The authors focused on the interface processes during the growth of nanowires (NWs) using the vapor-liquid-solid (VLS) mechanism and investigated the faceting of the NWs' sidewall surface. The study showed that faceting occurred when the wetting scenario of VLS growth was achieved at the sidewall surface. This faceting was caused by the emergence of oblique closed-packed faces at the crystallization front near the triple phase line. The control of sidewall faceting could be achieved through changes in the contact angle, introduction of impurities in the gas phase, or variations in temperature.

Summary: In this study, hexagonal boron nitride crystals were grown from Cu-Cr flux, with controlled growth atmosphere, source of raw materials, and crystallization cooling rate. The best quality crystals were obtained under diluted nitrogen atmosphere, using boron nitride crucible as source material, and a relatively low cooling rate. The growth mechanism on the smooth surface and the luminescence properties of the obtained crystals were also explored.

Summary: Fluorine-doped tin oxide (FTO) crystal structures with different morphologies and phase compositions were synthesized using the hydrothermal method. The addition of NH4F to the initial solution controlled the pH of the reaction mixture, resulting in changes in crystal shape and structure. The flower-like FTO structures obtained at a mass ratio of F/SnO2 = 0.05 showed the highest conductivity due to the misoriented primary nanocrystals and their local interaction, which are formed during the spontaneous growth under hydrothermal conditions.

Summary: A high-performance composite photocatalyst was prepared by using TiO2 nanoflowers dominated by high-energy {001} facets as template and Zn-Cu-In-Se (ZCISe) quantum dots (QDs) as sensitization material. The composite exhibited significantly improved photocatalytic abilities for Rhodamine B (Rh B) under visible light. The enhancements were attributed to the unique surface hetero-junctions and improved charge transport and separation characteristics.

Summary: In this study, a 2-inch diameter 4H-SiC single crystal was grown from a Si-Cr-C ternary solution with Al addition, and the surface morphology of the specimen was improved by optimizing the growth conditions. The SiC single crystal grown at 0.1 MPa of He gas showed a stable growth process with a hexagonal shape and a growth rate of about 152 μm/h, thanks to the appropriate thermal field distribution near the growth interface. The use of a specially designed seed holder wrapped by BN cap effectively suppressed the appearance of polycrystalline SiC and solvent inclusions in the grown crystal, but some pore or void defects were still present.

Summary: This article discusses the mechanism of structural hierarchy development during crystallization, as well as the driving forces behind it. It is found that crystallization pathways often involve monomer-by-monomer addition, with structural complexity arising from interfacial chemical coupling and fluctuation dynamics in the electric double layers.

Summary: Regular rhombic crystals have been synthesized via interface reaction using an 8-hydroxyquinoline derivative coordinated with Zn2+ ions. The crystal size can be controlled by the concentration of the ligand solution. The rhombic crystal exhibits a red-shifted absorption band and orange emission compared to the benzonitrile substituted 8-hydroxyquinoline ligand. Many stacked lamellas were observed in the synthesized crystal, formed by strong interaction forces induced by nitrile groups on the lamella surface.

Summary: The effect and mechanism of carrier gas velocity, V/III ratio, and carrier gas velocity match on the growth rate of AlN were investigated in this study. The results showed that the growth rate of AlN initially increased with hydrogen flow rate, reached saturation, and then decreased monotonically. The turning point value depended on the equipment and process. By increasing the MO VM, the growth rate of AlN could be improved, but the uniformity deteriorated due to turbulence and loss of uniform boundary layer. High quality AlN films were successfully grown on nano-patterned sapphire substrates with improved crystalline quality and atomic smooth surfaces.

Summary: This study investigates the melting process and nucleation behavior of sodium crystals using molecular dynamics simulation. The results show good agreement between simulated and experimental values for the melting temperature, density, and radial distribution function of sodium. The diffusion coefficient of liquid sodium increases linearly with temperature, and the homogeneous nucleation rate of melting in superheated sodium crystal exponentially increases with temperature. The findings provide theoretical support for applications involving heat and mass transfer in sodium-related systems.

Summary: Epitaxial V2O3 films were fabricated on sapphire substrates using mist chemical vapor deposition (mist CVD) method, eliminating the need for high vacuum conditions. The films can be grown on sapphire substrates even under atmospheric pressure, with the optimal growth temperature at 823 K. The films grown at 823 K exhibit a metal-insulator transition at approximately 155 K. The film on C-plane sapphire exhibits a lower transition temperature compared to those on R- and A-plane sapphire substrates.

Summary: The past two decades have witnessed a significant transformation in solar silicon crystal growth, especially in the competition between multi-crystalline silicon (Multi-Si) and mono-crystalline silicon (Mono-Si). The demand for this crucial material has exponentially surged, with silicon solar panels capturing over 95% of the global PV market share. The advancements in crystal growth technology during this period have set historical benchmarks, with the market share shifting from high-performance multi-crystalline silicon (HPM-Si) to CZ silicon.

Summary: This article discusses the novel fractal nature of hydrothermally synthesized MoS2 QDs. By adjusting the reaction time, the study found that the average size of QDs increases and then decreases with longer reaction times. STEM images indicate that shorter reaction times lead to sheet formation, while extended reaction times cause sheets to fragment into QDs.

Summary: The effect of growth temperature on the buffer leakage currents of GaN-on-Si layers was investigated. It was found that higher growth temperature results in lower leakage currents. The defects in GaN layers grown at different temperatures were studied using photoluminescence technique, and a correlation between leakage currents, structural perfection, and donor concentration in GaN-on-Si layers was established. It was also observed that reduced growth temperature leads to the formation of inversion domains.
