Summary: In this study, efficient photodetection of light from near-infrared to mid-wave infrared was achieved by engineering InAs nanowire arrays. By optimizing the nanowire growth temperature and V/III ratio, a high wurtzite density of about 67% was obtained in the nanowire arrays. Due to the formation of a p-n junction, the nanowire arrays exhibited an ultrawide room-temperature photoresponse ranging from 500 to 3500 nm under zero bias. The nanowire arrays also showed high responsivity and detectivity at a relatively high operating temperature of 150 K. This research demonstrates the potential of InAs nanowire arrays for the development of high-performance ultra-broadband infrared photodetectors for wavelengths ranging from NIR to MWIR.

Summary: In this study, a simple hydrothermal treatment was used to decorate CdS nanowires with Cu2MoS4 nanosheets as co-catalyst for photocatalytic H-2 evolution reaction. The Cu2MoS4/CdS nanocomposite exhibited excellent visible light-driven H-2 evolution activity, which was 18.8 times higher than pure CdS. The well-designed structure of Cu2MoS4/CdS and the effective separation of photogenerated electron-hole pairs in the nanocomposite contribute to its enhanced photocatalytic performance.

Summary: A lattice-matched heterojunction (CdS-Ag2S) with higher charge separation efficiency and longer carrier lifetime was constructed through ion-exchange epitaxial growth. Its built-in electric field and bulk-charge separation efficiency were significantly higher than that of the lattice-mismatched heterojunction (CdS-Ag2S-M). Furthermore, the lattice-matched CdS-Ag2S exhibited 3.4 times higher photodegradation efficiency towards norfloxacin compared to CdS-Ag2S-M. The research highlights the importance of improving lattice matching in heterojunctions for achieving high-performance photocatalysts.

Summary: The cooperativity between achiral CdSe/CdS nanorods (NRs) and chiral perylene diimide (PDI)-based molecules is built upon their coassembly. The encapsulation of NRs into PDI suprascrolls enables chirality transfer and leads to enhanced circularly polarized luminescence. The chirality of the nanocomposites can be inverted when NRs are self-assembled into chiral superlattices.

Summary: Efforts have been made to improve the photoresponsivity of plasmonic photodetectors. In this study, photodetectors based on transparent conductive oxide (TCO)/Semiconductor/Metal configuration, specifically with a roughened interface, were numerically investigated. The results show that a roughened structure effectively alleviates the momentum mismatch of hot electrons at the metal/semiconductor interface, resulting in improved injection efficiency and photoresponsivity. At the incidence wavelength of 1550 nm, the photoresponsivity increased by about 8 times. The influence on the resonant wavelength shift is negligible at nano-scale roughness. This work provides valuable guidance for theoretical and experimental research on plasmonic photodetectors.

Summary: The thermoelectric conversion process of SnSe and its catalytic effect in the degradation of methylene blue were studied. It was found that SnSe serves as a thermal catalyst for the efficient degradation of methylene blue, especially at high temperatures. The non-equilibrium carriers of SnSe at high temperatures create a built-in electric field along the temperature gradient, contributing to electron transport during the degradation process.

Summary: Cu-doped SnSe powder was synthesized by hydrothermal method, and the degradation effect of different doping concentrations on methylene blue was investigated. It was found that low doping concentrations did not show obvious degradation effect due to Cu dissolution in the SnSe lattice. With increasing doping concentration, SnSe transformed from a layered structure to a nanocluster structure with reduced particle size, and a mixed phase of SnSe and Cu2SnSe4 appeared. The catalytic degradation effect on methylene blue was significantly enhanced, and the best performance was achieved at a doping concentration of 10 wt.%.

Summary: This paper presents a method of introducing copper atoms into two-dimensional tellurium nanosheets through intercalation, thereby modifying their optical and electrical properties. The results show that the insertion of copper atoms increases the crystal plane spacing of the samples, and second-harmonic-generation studies reveal intrinsic anisotropic modes. Birefringent properties are observed using polarizing light microscopy. In addition, the intercalation leads to higher currents in the samples, but the gate control effect is lost.

Summary: In recent decades, low-dimensional nanodevices have shown great potential in extending Moore's Law. While n-type semiconductors have several candidate materials with high carrier transport and device performance, the development of their p-type counterparts remains a challenge. As a p-type narrow bandgap semiconductor, tellurium nanostructure exhibits outstanding electrical properties, controllable bandgap, and good environmental stability. With the controllable synthesis methods for various tellurium nanostructures, these materials have promising applications in next-generation electronics and optoelectronic devices. This review summarizes the controllable synthesis methods and recent progress in the application of tellurium nanostructures, focusing on their role in electronics and optoelectronics, such as field-effect transistors, photodetectors, and sensors. Moreover, the future challenges, opportunities, and development directions of tellurium nanomaterials are also discussed.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
