Summary: One-dimensional nanostructures such as nanowires exhibit enhanced photoresponse compared to bulk materials due to unidirectional transport reducing recombination and scattering of charge carriers. CuO and Cu2O are promising transition metal oxides for efficient UV and visible light detection, forming type-II heterojunction for charge separation. Core-shell CuO/Cu2O nanowires show superior performance in terms of responsivity and detectivity, attributed to the Ohmic junction at Pd-Cu2O interface and type II heterojunction at CuO/Cu2O interface.

Summary: Core-shell nanowire heterostructure is a new architecture for photodetector applications, which enhances light absorption and improves photodetector performance with enlarged active surface area. SnS2, as a coating material, has gained increasing interest in next-generation optoelectronic materials. In this study, the hydrothermally grown SnS2 and Si nanowire (SiNWs) core-shell heterostructure exhibited enhanced optoelectronic performance. The uniform coating of hydrothermally grown SnS2 on Si nanowire increased the effective junction area of the heterostructure, resulting in improved optoelectronic properties over a broad spectral range (300 - 1100 nm). Specifically, under 340 nm illumination, the core-shell photodetector showed high responsivity (-383 A/W) and extremely high external quantum efficiency (-2 x 105 %) at a low optical power (-20 nW/mm2). This SnS2/SiNWs core-shell heterostructure with significantly enhanced optoelectronic performance holds great potential for high-efficiency photodetector development.

Summary: In this study, we report the growth of a SiGe(P)/Si core/shell nanowire heterostructure using chemical vapor deposition and vapor-liquid-solid growth mechanism. The entire heterostructure behaves as a p-type semiconductor, with high-density carriers confined within the Si shell forming a tubular conduction channel. These findings are confirmed by calculations and the analysis of current-voltage characteristics. The microscopic analysis reveals a coherent epitaxial core/shell interface, with strain being released through the formation of dislocations along the axial direction of the heterostructure.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
