Summary: The presence of in-plane chiral effects and spin-orbit coupling in a TiS3(001) field-effect phototransistor is confirmed through changes in the photocurrent caused by left versus right circularly polarized light. NanoARPES measurements indicate that the direction of the photocurrent is protected by strong spin-orbit coupling and the anisotropy of the band structure. Dark electronic transport measurements show that TiS3 is n-type with an electron mobility ranging from 1-6 cm(2)V(-1)s(-1). I-V measurements under laser illumination demonstrate that the photocurrent exhibits bias directionality dependence similar to bipolar spin diode behavior. The presence of spin-orbit coupling in TiS3, a material without heavy elements, is attributed to the loss of inversion symmetry at the TiS3(001) surface.

Summary: In this study, we report the preparation of quasi-two-dimensional charge-density-wave material fillers for inkjet printing. The fillers were prepared by liquid-phase exfoliation of 1T-TaS2 crystals and dispersed in a mixture of isopropyl alcohol and ethylene glycol for inkjet printing. The printed thin films exhibited preserved charge-density-wave properties of 1T-TaS2. Furthermore, the functionality of the printed thin-film devices was determined by the charge-density-wave phase transition of individual filler particles.

Summary: By synthesizing the ternary composition chalcogenide Ta2NiSe7, the excellent electrical conductivity property was utilized to measure the breakdown current density according to thickness change. It was found that the breakdown current density reached 35 MA cm(-2) at 18 nm thickness, and through optimization of the exfoliation process, it is expected to increase to about 356 MA cm(-2). These low-dimensional materials with ternary compositions can be potential candidates for current-carrying materials needed for miniaturizing electronic devices.

Summary: A quasi-one-dimensional van der Waals metallic nanowire Nb2PdS6 was synthesized and its electrical characteristics were analyzed. The study found that Nb2PdS6 exhibited high crystallinity and a high breakdown current density. Moreover, the breakdown mechanism of the nanowires was attributed to Joule heating and was well described by a 1D thermal dissipating model.

Summary: This study focuses on the preparation of flexible polymer composite films with aligned metallic fillers composed of atomic chain bundles of tantalum triselenide (TaSe3). By mimicking the design of an electromagnetic aperture grid antenna, the nanoscale functionality is achieved. The results show that the electromagnetic transmission through such films can be significantly varied by changing the relative orientations of the quasi-1D fillers and the polarization of the electromagnetic wave, making these polarization-sensitive polymer films applicable for advanced electromagnetic interference shielding in future communication systems.

Summary: 1/f noise is the dominant source of noise in low-frequency range in various physical systems, offering valuable insights into the fabrication process and defect introduction. The study of bilayer MoS2 transistors on paper with inkjet-printed Ag contacts and hBN dielectric shows promising stability and comparable noise properties to those on SiO2. This suggests potential for the development of low noise 2D material-based flexible electronics on paper.

Summary: By introducing Ag into ZrTe3 through solid-state intercalation, a new crystal phase with a 1D octahedral structure and a quasi-amorphous (QA) phase during the structural transition are discovered. The transport properties can be flexibly modulated from superconductivity to semiconductivity depending on the Ag concentration. Density functional theory calculations reveal the attraction between Ag ions and the pair diffusion caused by their attraction. In addition, the attraction or repulsion between guest ions can predict whether to induce a QA phase or simply lattice expansion, as in the intercalation into 2D TMDs.

Summary: This study discusses low-frequency electronic noise in quasi-1D (TaSe4)(2)I Weyl semimetal nanoribbons. It is found that the noise spectral density follows the 1/f type and scales with the square of the current. The noise level increases by an order of magnitude near the temperature of 225 K and shows Lorentzian features. These changes are attributed to the charge-density-wave phase transition. The results provide insights into the electron transport in quasi-1D topological Weyl semi-metals and its potential applications as downscaled interconnects.

Summary: This study demonstrates a unique class of quantum composites based on polymers with fillers composed of a van der Waals quantum material. These composites reveal multiple charge-density-wave quantum condensate phases. Typically, materials exhibiting quantum phenomena are crystalline, pure, and have few defects. However, in this research, the macroscopic charge-density-wave phases of the filler particles are successfully preserved even after multiple composite processing steps. The prepared composites display strong charge-density-wave phenomena at temperatures even above room temperature and show potential for advanced applications in energy storage and electronics.

Summary: We investigated the low-frequency electronic noise in ZrS3 van der Waals semiconductor nanoribbons. The test structures were field-effect-transistors with an off n-channel and a high on-to-off ratio. The noise in ZrS3 nanoribbons showed a 1/f(gamma) spectral density with gamma = 1.3-1.4. We used light illumination to determine that the noise is due to generation-recombination caused by deep levels, and determined the energies of the defects acting as carrier trapping centers in ZrS3 nanoribbons.

Summary: In this study, we investigated the low-frequency electronic noise in beta-(AlxGa1-x)(2)O-3 Schottky barrier diodes. The noise spectrum exhibited 1/f behavior with Lorentzian bulges at intermediate current levels. The normalized noise spectral density was determined to be around 10(-12) cm(2)/Hz at a current density of 1 A/cm(2) and a frequency of 10 Hz. We observed random telegraph signal noise at intermediate currents, which was attributed to defects near the Schottky barrier.

Summary: In this study, the authors investigate the thermal conductivity of graphene composites at different temperatures. They find that the thermal conductivity can be both higher and lower than that of pure epoxy, depending on the graphene filler loading and temperature. They explain this counter-intuitive trend by the increasing effect of thermal boundary resistance at cryogenic temperatures and the anomalous thermal percolation threshold.

Summary: This study proposes a highly tunable gas sensor strategy by combining MXene with a sacrificial material that can be controlled oxidized to form oxide nanoparticles, altering sensing response. The controlled annealing process retains the integrity of MXene sheets while converting the sacrificial material to a metal oxide, fine-tuning the sensor properties. The approach is demonstrated using Ti3C2Tx MXene mixed with TiS3, showing improved sensor response to ethanol. The addition of TiS3 allows for the preservation of MXene as the sensor material and the tuning of sensor properties through annealing for specific analytes or applications.

Summary: This study investigates the temperature dependence of current fluctuations in thin films of quasi-two-dimensional 1T-TaS2 van der Waals material. The current fluctuations appear prominently at electric fields corresponding to transitions between charge-density-wave phases and at the onset of charge density wave domain depinning. The depinning threshold field, ED, increases monotonically with decreasing temperature and film thickness, indicating surface pinning of charge density waves.

Summary: This study investigates the temperature dependence of low-frequency electronic noise in NiOx/beta-Ga2O3 p-n heterojunction diodes. The results show that the noise spectral density follows a 1/f-type behavior at room temperature, but exhibits Lorentzian components at higher temperatures and current levels. Interestingly, the noise shows a non-monotonic dependence on temperature near T = 380 K. Raman spectroscopy reveals material changes above this temperature, leading to reduced noise. The normalized noise spectral density of these diodes is determined to be on the order of 10(-14) cm(2) Hz(-1) (f = 10 Hz) at 0.1 A cm(-2) current density. In terms of noise level, NiOx/beta-Ga2O3 p-n diodes perform excellently for new technology and occupy an intermediate position among devices with different ultra-wide-bandgap semiconductors. These findings contribute to the understanding of the electronic properties of NiOx/beta-Ga2O3 heterojunctions and promote the development of noise spectroscopy as a quality assessment tool for new electronic materials and device technologies.
