Summary: This study focuses on the fabrication and characterization of electronic devices printed with inks of quasi-one-dimensional van der Waals materials. The temperature-dependent electrical measurements show that electron transport in the printed devices is dominated by electron hopping mechanisms. The low-frequency electronic noise in the printed devices is of 1/f'-type, with gamma close to 1 near-room temperature, indicating the potential of quasi-1D van der Waals materials for applications in printed electronics.

Summary: The study investigates the low-temperature direct current charge transport mechanism in PAN-WO3 nanocomposite. The inclusion of WO3 shifts the hopping dimensionality from 3-D to 1-D, leading to enhanced conductivity. The enhanced sensing behavior towards hydrazine in PAN-WO3 nanocomposite is attributed to its higher conductivity and intra-chain charge transport.

Summary: The production of energy using renewable energy sources and its storage is receiving attention due to the depletion of fossil fuels and growing energy demands. Electrochemical capacitors with high specific capacitance, power density, cyclic stability, and fast charging-discharging rates have become important for energy storage. Many researchers have focused on developing one-dimensional nanostructure electrode materials to enhance the energy storage ability of electrochemical capacitors, with conducting polymer nanostructures being highly desirable. However, their low specific capacitance and poor cyclic stability can be overcome by developing conducting polymer-based composites.

Summary: In nanostructure assemblies, the superposition of current paths forms microscopic electric circuits, and modifying these circuits through topological modifications enable the detection and enrichment of computational resources within transistors. By switching the ferroelectric polarization of the gate dielectric, the output polymorphism can be decoded, and the channel coherence can be tailored to achieve single-electron readout. The adjustment of current networks within transistors and their interaction with ferroelectric polarization lays the groundwork for generating diverse current characteristics for optimization-based computing.

Summary: Two-dimensional 4H-polytype tin disulfide (SnS2) flakes were synthesized and exfoliated into bilayers using the chemical vapor transport technique and mechanical exfoliation technique, respectively. The exfoliated layers exhibited high on/off ratio and mobility, but low mobility in the 4H-SnS2 FET devices indicated an insulating state. The optical bandgap energies of the 2D SnS2 single-crystal layers were significantly widened in the bilayers and tri-layers, offering potential for downscaled nanoscale semiconducting devices.

Summary: This review examines the switching mechanisms in memristive devices based on van der Waals materials, highlighting their potential advantages and the challenges that must be addressed for their use in next-generation electronic and computing applications. The modulation of structural defects or compositional impurities, also known as imperfections, mainly drives the memristive switching processes in these devices. The study explores how imperfections in van der Waals materials create different switching mechanisms, allowing for opportunities to engineer the switching behavior in memristive devices. The challenges of material selection, mechanism investigation, and switching uniformity control are discussed, along with the potential application of van der Waals memristors in efficient computing technologies at the system level.

Summary: Phosphorene and silicene, the new single-element two-dimensional materials, have remarkable physical properties but are hindered by air vulnerability. A new material called tellurene has been successfully synthesized, which exhibits outstanding electrical mobility and long-term stability in the air. The addition of chloride (TeCl4) to TeO2 promotes the growth of tellurium on a SiO2/Si substrate, resulting in stable tellurene flakes. The thermal properties of tellurene have been investigated using scanning thermal microscopy (SThM) for the first time, revealing abnormal thermal conductance across grain boundaries and a thickness-dependent thermal transport behavior. Furthermore, tellurene-based field effect transistors (FETs) exhibit temperature-dependent behavior that follows the 2D variable-range hopping (VRH) model.
