Summary: A simple oxidation method was used to prepare CuO nanodisks on a flexible Cu sheet, with the crystal structure and surface morphology analyzed using various techniques. The in situ transformation of nanodisk surface after recycling accelerated dye degradation due to electron transfer. Efficient charge carrier separation was observed in the photodegradation system of Cu/CuO nanodisks, which was attributed to the generation of superoxide radical under daylight irradiation.

Summary: In this study, heterostructured BiOCl-LaOCl composites were synthesized using KCl as a source of chlorine and varying contents of LaOCl as raw materials in the presence of ethylene glycol at a temperature of 100 degrees C by using the solvothermal method. The prepared composites were characterized and showed excellent photocatalytic activity for degrading Rhodamine B dye under sunlight irradiation. The BiOCl-LaOCl-1 composite exhibited the highest catalytic activity among all the synthesized materials, with a reaction rate four and six times higher than those of BiOCl-LaOCl-2 and BiOCl, respectively. The scavenger test results indicated that superoxide and hole radicals were mainly responsible for the photodegradation, and the high BET surface area of the composite also contributed to its enhanced photocatalytic activity.

Summary: A PVA aerogel/TiO2/MoS2/Au catalyst prepared by hydrothermal method was used for the degradation of Rhodamine B. The composite showed a uniform and well-structured porous network structure, high specific surface area, and large pore diameter. It had a high absorption rate in the visible light range and effectively inhibited the recombination of photogenerated electron-hole pairs due to the formation of a heterojunction. The composite material exhibited excellent photocatalytic performance, achieving a degradation rate of 86% in two hours. The PVA-supported photocatalysts were easily recoverable and maintained high catalytic activity even after 5 recycles.

Summary: The electrical properties of carbon interstitials (C-i) in 4H-SiC have been investigated in this study. Excess carbon was introduced into low-doped n-type 4H-SiC epilayers and new levels related to C-i were observed. The properties of these levels were found to be different from those of the M center, suggesting a diverse variety of C-i-related defects. This research provides insights into the microscopic process of vacancy annihilation during carbon injection processes.

Summary: In this study, the phenomenon of polymorphism in gallium oxide is investigated. It is found that the amorphization can be significantly suppressed by the phase transition, leading to the fabrication of a highly oriented single-phase film. A novel mode of lateral polymorphic regrowth, not previously observed in solids, is also discovered. These findings open up new directions for research on polymorphs in Ga2O3 and potentially in other materials.

Summary: The fabrication of SiC junction barrier Schottky diodes involves Al ion implantation for p-type doping. By using a new fabrication method, it has been found that low temperature annealing followed by thermal oxidation can solve the trade-off between high Al acceptor activation and low residual concentration of carbon vacancies. This results in the suppression of carbon vacancies and a significant reduction in the reverse leakage current.

Summary: Ion implantation is an effective method for introducing defects into semiconductors. In this study, we investigated the use of crystallographically aligned implants to control the balance between optically active defects in ZnO. Optical data and structural analysis confirmed the formation of different dominant crystalline defects in samples implanted along and off the [0001] direction. The proportions of extended and point defects in the initial as-implanted states of these samples were found to significantly influence the defect-related luminescence upon annealing. We conclude that channeling implants have value in functionalizing defects in semiconductors by tuning specific spectral contents in defect-related emission bands.

Summary: Carrier lifetime control of 150 μm thick 4H-SiC epitaxial layers via thermal generation and annihilation of carbon vacancy (V-C) related Z(1/2) lifetime killer sites is achieved. The defect development during SiC processing steps is monitored using electrical characterization techniques and a novel all-optical approach. The lifetime control is realized by initial high-temperature treatment to increase V-C concentration followed by a moderate-temperature post-annealing. A significant increase in lifetime is observed after the post-annealing, indicating the reduction of V-C-related Z(1/2) sites.

Summary: Significant resistivity variations have been observed in oxides subjected to low ion doses, which cannot be explained by bulk defects. A comparative study of In2O3-based oxides revealed correlations between resistivity evolution, low ion doses, and UV illumination. The resistivity drops were attributed to oxygen desorption facilitated by irradiation/illumination, as confirmed by post-irradiation exposure to oxygen atmosphere.

Summary: II-IV nitrides and their alloys are a potentially cost-efficient alternative to the well-developed AlN-GaN-InN system. However, ZnSnN2, the lowest band gap material, has high carrier concentrations, limiting its potential use in solar cells and LEDs. This study explores the use of lithium (Li) as a dopant to improve the electronic properties of ZnSnN2. Other possible dopants, such as In, Ga, Al, and B, are also investigated.

Summary: Ion beam fabrication of metastable polymorphs of Ga2O3, assisted by the controllable accumulation of the disorder in the lattice, is explored for its alternative approach to conventional deposition techniques. In this study, two strategies - ion implantation of silicon donors and plasma treatment with hydrogen - are investigated for tuning the electron concentration in the ion beam created metastable kappa-polymorph. The results show that silicon doping did not change the high resistive state, while hydrogen plasma treatment converted the ion beam fabricated kappa-polymorph to n-type conductivity.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
