Summary: Understanding the relationship between molecular geometry and electronic properties of single-molecule junctions is challenging. In this study, we investigated this relationship by applying a sinusoidal modulation to the molecular junction electrode position. We found that junctions formed with molecules having different molecule-electrode interfaces exhibited statistically distinguishable Fourier-transformed conductances. Our findings suggest that voltage-modulated van der Waals interactions play a significant role in the conductance of single-molecule junctions.

Summary: 2D monolayers can be vertically stacked in van der Waals heterostructures to support a wide range of confined polaritons. This offers advantages in terms of controlling the constituent layers, stacking sequence, and twist angles. These heterostructures have extended the performance and functions of polaritons, and potential applications include nanophotonic integrated circuits.

Summary: Layered crystals, such as tungsten diselenide, can exhibit unconventional optical properties that allow for the propagation of subdiffractional waveguide modes with hyperbolic dispersion. This study demonstrates optically induced hyperbolicity in WSe2 and explores the role of quantum transitions of excitons in the observed polaritonic response.

Summary: An effective molecule optimization strategy has been reported to upgrade van der Waals (vdWs) contacts, achieving near-zero Schottky barriers and creating high-performance electronic devices. The strategy induces defect healing effect and enhances hole density in p-type semiconductors, effectively thinning the Schottky barrier width and improving carrier interface transmission efficiency. The optimized contacts demonstrate an ultrathin Schottky barrier width and outstanding contact resistance, leading to an ultrahigh field-effect mobility in WSe2 flakes.

Summary: Controlling matter-light interactions with cavities is crucial in modern science and technology. By integrating MoSe2-WS2 heterobilayers in a microcavity, cooperative coupling between moire-lattice excitons and microcavity photons has been established, providing versatile control of both matter and light. This moire polariton system combines strong nonlinearity and microscopic-scale tuning of matter excitations, offering a platform to study collective phenomena from tunable arrays of quantum emitters.

Summary: With the continuous advancement of nanofabrication techniques and the discovery of useful manipulation mechanisms in high-performance applications, the morphology and usage of junction devices in photodetectors have undergone fundamental revolution. New types of photodetectors, not relying on any junction, have emerged, offering high signal-to-noise ratio and multidimensional modulation. This review focuses on a unique category of material systems, van der Waals materials, which support novel high-performance photodetectors beyond junctions.

Summary: In this study, semimetallic transition metal dichalcogenides (TMDCs) 1T-WTe2 were used as electrodes to fabricate WTe2/metalated tetraphenyl-porphyrin (M-TPP)/WTe2 junctions via van der Waals interaction. Compared to chemically bonded Au/M-TPP/Au junctions, the conductance of these M-TPP van der Waals molecular junctions was enhanced by 736%. Moreover, the WTe2/M-TPP/WTe2 junctions exhibited a tunable conductance range of 10^(-3.29) to 10^(-4.44) G through single-atom control, recording the widest tunable range of conductance for M-TPP molecular junctions. This work demonstrates the potential of two-dimensional TMDCs in constructing highly tunable and conductive molecular devices.

Summary: A quadratically nonlinear photodetector (QNPD) composed of a van der Waals (vdW) stacked GaSe/InSe heterostructure is reported in this study. The QNPD exhibits unique electronic and optical attributes and extends the photodetection wavelength range from 900 to 1750 nm due to the extra second-harmonic generation (SHG) process in GaSe/InSe. It is highly sensitive to the variation of optical intensity and can be used as an autocorrelator for measuring ultrafast pulse widths and an optoelectronic mixer for signal processing.

Summary: By breaking traditional alloying strategy restrictions, the high entropy concept has expanded the field of alloy exploitation. This review focuses on the combination of the high entropy concept and van der Waals systems to create a new category of materials called high entropy van der Waals materials (HEX). The design strategy for HEX incorporates the local features of high entropy materials and the holistic degrees of freedom in van der Waals materials, successfully leading to the discovery of various high entropy compounds with desirable physical properties. Additionally, deliberate design of structural units and their stacking configuration in HEX can also enhance catalytic performance.

Summary: We present a classical induction model to evaluate the three-body ion-water-water (I-W-W) and water-water-water (W-W-W) interactions in aqueous ionic systems. The accuracy of the classical model is benchmarked against an accurate dataset, and it demonstrates excellent agreement with the reference second order Moller-Plesset and coupled-cluster single double and perturbative triple [CCSD(T)] three-body energies.
