Summary: The authors of the article presented a novel method for preparing high-quality monolayer MoSe2 films and demonstrated a wafer-scale, gate-tunable photodetector array with superior optoelectronic properties using a growth promoter-assisted growth strategy. The MoSe2 film synthesized with this method showed improved crystallinity compared to the films without the growth promoter, leading to enhanced photodetector performance. The resulting photodetector array exhibited higher photoresponsivities over visible wavelengths than previously reported devices based on CVD-synthesized monolayer TMDs.

Summary: This study demonstrates direct growth of MoSe2 films on selective pattern areas via a surface-mediated liquid-phase promoter using a solution-based approach, resulting in highly uniform films and the ability to produce other TMD films. The approach also allows control over various pattern shapes, sizes, and large-scale areas, improving applicability in future devices. The patterned MoSe2 field-effect transistor device exhibits a p-type dominant conduction behavior with a high on/off current ratio, providing guidance for future design of integrated devices for large-scale application.

Summary: In this study, nickel-doped molybdenum diselenide nanosheets were successfully synthesized and integrated with carboxylated multiwalled carbon nanotubes, forming a composite material. The prepared nanocomposite showed excellent catalytic performance as an electrochemical catalyst for methanol oxidation reaction. It exhibited a low onset potential and high activity, and maintained 90% of its activity even after a long duration of time. Therefore, the nickel-doped molybdenum diselenide/carboxylated multiwalled carbon nanotubes composite is a promising and cost-effective anode catalyst for methanol oxidation reaction.

Summary: We demonstrate dynamic beam steering by an active van der Waals metasurface utilizing the excitonic resonances of monolayer molybdenum diselenide (MoSe2). By controlling the radiative and nonradiative rates of excitons, we can dynamically control the reflection amplitude and phase profiles, resulting in an excitonic phased array metasurface. This approach shows potential for wavefront shaping in emerging photonic applications.

The morphology of MoS2 was found to be dependent on the dopant concentrations, with a flower-like morphology observed at higher doping concentrations.

Summary: Recently, it has been found that halide salts can promote the chemical vapor deposition (CVD) growth of two-dimensional transition metal dichalcogenides (TMD). In this study, the molecular mechanisms during the salt-assisted CVD growth of MoS2 monolayers were investigated using first-principles calculations and ab initio molecular dynamics (AIMD) simulations. The sulfurization of molybdenum oxyhalides was explored and found to have much lower activation barriers than molybdenum oxide, which is present during conventional saltless growth. The rate-limiting barriers were found to depend linearly on the electronegativity of the halogen element, with oxyiodide having the lowest barrier. This study reveals the promoting mechanisms of halides and allows growth parameter optimization for faster growth of MoS2 monolayers in CVD synthesis.

Summary: In this study, researchers investigated the electronic structure changes of MoS2 nanosheets during the carbon dioxide reduction reaction (CO2RR) through experimental and computational methods. They discovered the existence of Mo-CO2 binding in the active state, which perturbs the hybridized Mo 4d-S 3p states and is influenced by electrochemically induced sulfur vacancies. These findings provide insights into the excellent performance of MoS2 in CO2RR and could be used as a screening criterion for improving the activity and selectivity of transition-metal dichalcogenides (TMDCs) in general.

A multilayer structure based on patterned Al/ZnO/Si has been designed using the finite-element method (FEM) to facilitate the application of SAW devices in integrated circuit technology. The dependence of ZnO piezoelectric material on the electromechanical coupling factor has been systematically studied, showing that the Al/ZnO/Si structure excites high electromechanical coupling factors for both the Rayleigh mode and Sezawa mode. The temperature characteristics of the structure have also been studied, with SiO2 used as an intercalation layer for temperature compensation.

Summary: In this study, 0.5Ba(Zr0.2Ti0.8)O3-0.5Ba0.7Ca0.3TiO3(0.5BZT-0.5BCT) thin films were deposited on Pt/Ti/SiO2/Si substrate, followed by the deposition of small area Fe65Co35(FeCo) films on the 0.5BZT-0.5BCT films. The hysteresis loops and piezoelectric curves of the 0.5BZT-0.5BCT films were investigated. The results showed that the 0.5BZT-0.5BCT films exhibited a piezoelectric displacement of 63 angstrom, residual polarization intensity of 2.76 mu C/cm2, and coercive field of 110 kV/cm. The 0.5BZT-0.5BCT/FeCo composite films showed magnetic hysteresis loops and stripe-like domains, with in-plane and out-of-plane coercivities of 10 Oe and 94 Oe, respectively, indicating good soft magnetic properties of the thin films. The current-voltage (I-V) curves of the FeCo films on 0.5BZT-0.5BCT films were studied, and the thin films exhibited resistance switching behavior, with a maximum resistance change of 94% at 10 V bias voltage and 1 V scan voltage.

Summary: In this work, homogeneous monolayer MoS2 films with high crystalline quality were prepared, and back-gate field-effect transistors (FETs) were fabricated by inserting an ultrathin Al2O3 interlayer between the metal electrodes and MoS2 nanosheets. The addition of the ultrathin Al2O3 interlayer significantly reduced contact resistance and Schottky barrier height, increased switching ratio, on-current, and field-effect mobility. The Al2O3 interlayer also protected the channel materials and reduced the Fermi level pinning phenomenon. FETs with Al2O3 interlayers showed excellent stability and repeatability, providing effective references for future electronic devices.

Summary: Film size dependent bias voltage modulated resistance switching behavior of a novel memory cell constructed with ultra-thin FeCo thin films grown on PMN-PT single crystal piezoelectric substrates was reported. The PMN-PT exhibited good ferroelectric properties and excellent piezoelectric performance. By applying a bias voltage in the thickness direction, the I-V characteristics of the FeCo films could be adjusted and multiple resistance states were generated. The resistance switching behavior was enhanced by using small lateral size FeCo films.

Summary: We proposed a compact and tunable multimode interferometer based on an asymmetric wavy fiber, which can be fabricated by non-axis pulling processes of single-mode fiber. Theoretical and experimental analyses confirmed its tunable multimode propagation. The AMWF showed a nonlinear wavelength response with increasing axis displacement, reaching a maximum sensitivity of -1.33 nm/μm in the range of 0-10 μm. The cost-effective and tunable properties of the AMWF make it a promising platform for micro-nano photonic devices and optical sensing applications.

Summary: This paper proposes a tunable and switchable absorber based on photoconductive silicon (Si) and vanadium dioxide (VO2). The absorber achieves tunable bifunctional single-/dual-band absorption and switchable perfect absorption by optically pumped silicon and temperature controlled VO2. The absorption mechanism is explained by relative impedance theory. Additionally, a multiple interference model based on quasi-Fabry-Pe' rot cavity resonance is established to further understand the principle of absorption, and the theoretical result agrees well with the numerical ones. The influence of structural parameters, polarization, and angle of incident wave on absorption performances are systematically studied. The flexible tunable characteristics and polarization insensitivity of the designed absorber have potential applications in dynamic terahertz (THz) devices.

Summary: This study presented the synthesis of petal-like Cu2WSx nanosheet structures supported on carbon paper by a simple one-step solvothermal method. Cu2WSx microstructures with different morphologies were obtained by solvothermal vulcanization of thioacetamide at different concentrations. Cu2WSx/CP exhibited superior electrocatalytic performance as the counter electrode in DSSCs, achieving a photoelectric conversion efficiency of 9.01%. The morphology of Cu2WSx was influenced by sulfide concentration, which in turn affected the specific surface area and catalytic activity of the material. This work highlights the potential of Cu2WSx/CP as a cost-effective substitute for Pt counter electrode materials in DSSCs.
