Summary: Black silicon (b-Si) with its promising optical, electronic and structural properties has attracted great attention for a wide range of applications. In this study, a technique involving thermal oxidation, photoresist coating, and chlorine plasma etching was used to produce b-Si and investigate its radiative recombination dynamics. The results showed the presence of a no-phonon radiative recombination component competing with non-radiative recombination at surface defects. The emission exhibited two decay processes with a peak energy at around 480 nm, a fast component of about 15 ps, and a lifetime component of around 50 ps, as well as a slow process in the red spectral region with a time constant of 1500 ps.

Summary: In this study, scintillating nanoparticle composite films of Ce3+-doped Y3Al5O12 (YAG:Ce) embedded in a polystyrene (PS) polymer were successfully prepared. X-ray diffraction analysis confirmed the successful synthesis of YAG:Ce powders. The composite films exhibited higher glass transition temperature and thermal degradation temperature compared to pure PS. Photoluminescence measurements showed that the emission characteristics of Ce3+-doped YAG phosphors varied with the mass ratio of YAG:Ce nanoparticles and the concentration of the polymer solution.

Summary: This study investigates the optical properties and carrier dynamics of n-type wurtzite InN with different surface dimensions using photoluminescence and time-resolved photoluminescence analysis. The morphology of InN can be controlled by growth temperature, leading to variations in carrier concentration and emission peak energies. The increase in carrier concentration in InN samples with 2D features is attributed to the presence of donor-like nitrogen vacancies, while the higher emission peak energies are explained by the recombination of Mahan excitons and localized holes in different dimensional structures.

Summary: Chalcogenide-based semiconductors are highly promising for optoelectronic devices due to their low toxicity, cost-effectiveness, stability, and tunable properties. However, limited understanding of charge recombination mechanisms and trap states hinders their development. A comprehensive study on bismuth-based chalcogenide thin films was conducted to investigate the influence of post-treatments. The key findings were that post-treatment with Bi enhanced crystallinity and mobility but also increased carrier density, while post-treatment with sulfur increased carrier lifetime and mobility by passivating trap states.

Summary: CdTe solar cells are the leading thin-film photovoltaic technology due to their low cost and high reliability. Increasing the open-circuit voltage by reducing recombination is a promising way to further improve efficiency. Advanced analysis techniques have identified defect-mediated recombination as the dominant mechanism for voltage losses in Cu-doped CdSe/CdTe solar cells. Additionally, the use of Al2O3 has been shown to increase carrier lifetimes and quasi-Fermi-level splitting, potentially overcoming the long-standing 900 mV voltage limitation.

Summary: The recombination dynamics of BxGa1-xAs alloys grown on GaAs (001) by metal-organic chemical vapor deposition (MOCVD) were investigated through steady-state photoluminescence and Time-Resolved Photoluminescence (TRPL) measurements. The decay time was found to vary depending on emission energy, sample geometry, and post-growth treatment. Exciton dynamics in boron-based ternary alloys were influenced by temperature, with different mechanisms dominating at low, intermediate, and high temperatures. The research findings highlighted the importance of bandgap inhomogeneity and below-band gap states for carrier relaxation dynamics in BxGa1-xAs/GaAs alloys.

Summary: This study investigates a family of compositionally complex cubic spinel ferrites, exploring their average and local atomic structures, chemical short-range order, magnetic spin configurations, and magnetic properties. The results show that all compositions exhibit ferrimagnetic average structures with similar local bonding environments, but they display varying degrees of cation inversion and apparent bulk magnetization. The analysis of magnetic reversal behavior reveals different degrees of magnetic ordering and interactions, including potential local frustration. Additionally, the relationship between the degree of cation inversion and spin collinearity is demonstrated through reverse Monte Carlo modeling. These findings are correlated with differences in synthesis procedures.

Summary: Evaluation of Ti-6Al-4V material deposited by AFSD on rolled Ti-64 base plate revealed different stress-strain responses between base plate and AFSD regions. Microstructure gradients observed by optical microscopy and spatially resolved PXRD rationalized these differences. AFSD regions exhibited a characteristic basket weave α-Ti microstructure, while the base plate showed a globular α+6 microstructure. Control of prior 6 microstructure using targeted deposition parameters will be critical for achieving desired properties using AFSD with titanium alloys.

Summary: We report a catalyst with vanadium oxide dispersed onto hexagonal boron nitride (h-BN), which catalyzes the oxidative dehydrogenation of propane (ODHP) via the Eley-Rideal mechanism and the Mars-van Krevelen mechanism. The results show that loading 0.5wt% V significantly improves the yield of light alkene. Adding an appropriate concentration of nitric oxide further enhances the catalytic performance. This provides a potential strategy for developing efficient h-BN-based catalysts for ODHP by coupling gas-phase and surface reactions.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.
