Summary: In this article, the van der Waals epitaxial growth of ZnO layers on mica substrates is demonstrated through a low-temperature hydrothermal process. The addition of sodium citrate into the growth solution significantly promotes the lateral growth of ZnO crystallites, resulting in coalesced and continuous epitaxial layers. The combination of Mist-CVD process further improves the epitaxial quality and surface morphology of the hydrothermally grown ZnO layers.

Summary: Fluorite-structured Hf0.5Zr0.5O2 (HZO) thin films have gained attention for their good CMOS-compatibility and robust ferroelectricity. However, the challenges of high leakage current and poor endurance hinder the application of HZO in microelectronic devices. This study investigates the electric properties of Pt/HZO/La0.7Sr0.3MnO3 (LSMO) heterostructures and finds that the leakage mechanism is dominated by Schottky emission. By post-annealing in oxygen atmosphere, the barrier height can be increased, effectively reducing leakage current and improving endurance.

Summary: Efforts to integrate ferroelectric materials into nonvolatile, low energy consuming memories have focused on perovskite oxide materials. However, finite-size effects hinder their down-scaling for nanodevices, and alternative materials with robust polar properties are needed. Layered ferroelectrics of the Aurivillius phase have emerged as promising candidates with robust polarization at subunit-cell thicknesses, but controlled growth in epitaxial thin film form remains challenging. Here, the stabilization of coalescent layer-by-layer growth mode for Aurivillius family homologues is demonstrated, providing a systematic framework for the integration of high-quality epitaxial layered ferroelectrics into oxide electronics.

Summary: This paper reports the heteroepitaxial growth of (00.1)-oriented Zn2GeO4 thin films on c-plane sapphire substrates using pulsed laser deposition. The thin films exhibit [11.0] Zn2GeO4// [11.0] Al2O3 and [1(1) over bar.0] Zn2GeO4//[1(1) over bar.0] Al2O3 in-plane orientation relationships. The measured properties include a rocking curve full width at half maximum of 0.35 degrees, a direct bandgap of 4.9 +/- 0.1 eV, and a defect-related photoluminescence emission centered at 2.62 eV with a FWHM of 0.55 eV. This study enhances our understanding of the physical properties and potential device application of Zn2GeO4 thin films.

Summary: Integration of functional complex oxides with nanoelectronic devices has become a topic of great interest. However, integrating them with Si-based devices is challenging due to material and processing compatibility issues. In this study, a buffer stack of TiN/SrTiO3/CeO2 was used to successfully integrate the BFMO layered supercell phase on Si with high epitaxial quality. The microstructure, magnetic, ferroelectric, and optical properties of BFMO films on Si were characterized and compared with those on SrTiO3 single-crystal substrates, showing comparable epitaxial quality and physical properties.

Summary: Piezoelectricity is a highly functional property that has been widely studied in various applications, including piezoelectric catalysis and mechanical energy harvesting. In this work, (K0.5Na0.5)(0.94)Li0.06NbO3 (KNN6L) piezoelectric powders were combined with polydimethylsiloxane (PDMS) to develop flexible and recyclable KNN6L-PDMS porous piezoelectric composites. These composites demonstrated a degradation rate of approximately 91% for Rhodamine B dye wastewater under mechanical vibration, and the piezocatalytic activity remained excellent even after multiple decomposition cycles. Furthermore, COMSOL simulations confirmed the relationship between piezoelectric potential and piezocatalysis. The content of piezoelectric powders positively affected the magnitude of the generated piezoelectric potential. The catalytic mechanism was attributed to the generation of reactive oxygen species, such as center dot O-2(-) and center dot OH, in a water environment due to the strong piezoelectric effect of the porous composites. The flexible and recyclable porous piezoelectric composites exhibited outstanding performance in piezoelectric catalysis, which holds great promise for environmental remediation applications.

Summary: This passage mainly discusses that defect engineering is an important method for modifying semiconductors, but the introduction of the right quantity of defects in the right chemical environment is crucial for desirable results. The catalytic performance of g-C3N4 produced by direct condensation of nitrogen-rich precursors in N-2 atmosphere is often unsatisfactory due to the introduction of numerous defects, but the relationship between the formation of defects and the N-2 atmosphere is rarely explained, and controlling the quantity of defects is difficult. The proposed method reduces the quantity of defects in g-C3N4 synthesized by calcinating in N-2 atmosphere by protonating the precursor, leading to improved photocatalytic property.

Summary: This paper presents an efficient strategy for exposing unsaturated edge Ag on the surface of photocatalysts, forming Ag@g-C3N4 heterojunction. The introduction of Ag nanospheres into g-C3N4 enlarges the distance between g-C3N4 nanolayers and increases the exposure of Ag nanospheres. The Ag@g-C3N4 heterojunction provides polyunsaturated edge Ag as active sites and forms unique charge transfer channels, resulting in prolonged lifetime of photogenerated electrons.

Summary: The fracture and crack growth of materials can be predicted using numerical analysis and linear elastic fracture mechanics. In this study, experimental work supported by a numerical technique is presented to simulate crack propagation in a coating made from Fe-based amorphous material. The effects of mixed-mode loading on cohesive zone parameters are examined, and two failure criteria (maximum energy release rate and maximum tensile stress) are evaluated. The results show that both criteria are successful in predicting crack propagation in the Fe-based amorphous material.
