Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

Temperature dependent anisotropy and two-band superconductivity revealed by lower critical field in organic superconductor κ-(BEDT-TTF)2Cu[N(CN)2]Br

Resistivity and magnetization have been measured at different temperatures and magnetic fields in organic superconductors κ-(BEDT-TTF)2Cu[N(CN)2]Br. The lower critical field and upper critical field are determined, which allow to depict a complete phase diagram. Through the comparison between the upper critical fields with magnetic field perpendicular and parallel to the conducting ac-planes, and the scaling of the in-plane resistivity with field along different directions, we found that the anisotropy Γ is strongly temperature dependent. It is found that Γ is quite large (above 20) near Tc, which satisfies the 2D model, but approaches a small value in the low-temperature region. The 2D-Tinkham model can also be used to fit the data at high temperatures. This is explained as a crossover from the orbital depairing mechanism in high-temperature and low-field region to the paramagnetic depairing mechanism in the high-field and low-temperature region. The temperature dependence of lower critical field Hc1(T) shows a concave shape in wide temperature region. It is found that neither a single d-wave nor a single s-wave gap can fit the Hc1(T), however a two-gap model containing an s-wave and a d-wave can fit the data rather well, suggesting two-band superconductivity and an unconventional pairing mechanism in this organic superconductor.

Universal phonon softening in the pseudogap state of Tl2Ba2Can−1CunO2n+4+δ

Exploring the origin of the pseudogap is important for the understanding of superconductivity in cuprates. Here we report a systematical experimental study on the phonon vibrational properties of Tl2Ba2Can−1CunO2n+4+δ (n=1,2,3) single crystals based on the Raman scattering measurements over the temperature range from 10–300 K. The temperature evolution of the frequency and linewidth of the observed phonon modes in each member of this family does not follow the expected self-energy effect when entering the superconducting state. The anomalies are observed for the phonon modes involving the vibrations of the atoms in the Tl-O layer and the apical oxygen at the temperature around 150 K, which is higher above the superconducting transition. The phonon mode of the apical oxygen exhibits a pronounced universal softening behavior. From the comparison with the existing experimental data for various orders, we find that the observed starting temperature for the phonon softening corresponds to the onset opening temperature of the pseudogap. This finding indicates a large lattice effect in the pseudogap state and the non-negligible spin-phonon coupling for such a phonon softening.

We report on the quantum criticality of YbCu4Ni as revealed by our combined micro- and macro-measurements. We determine the crystal structure of YbCu4Ni with site mixing by neutron diffraction measurements, which suggests the possible presence of Kondo disorder. However, decreasing the local spin susceptibility distribution and the development of spin fluctuations below 10 K at ambient pressure by muon spin rotation and relaxation measurements suggests that YbCu4Ni exhibits quantum criticality. Therefore, our experimental results indicate that YbCu4Ni is a material that exhibits quantum criticality under zero magnetic field and ambient pressure.

Correction to: Nature Energyhttps://***/10.1038/s41560-024-01672-x, published online 15 November 2024. In the version of the article initially published, we mistakenly listed the environmental score for DMSO as 4 instead of the correct score of 5, based on the evaluation criteria outlined by CHEM21. This error, along with the transposition of the "NMP" and "DMPU" labels on the x axis, has been corrected in Fig. 1a, as seen below in Fig. 1. (Figure presented.) Original and corrected Fig. 1a. To ensure clarity and accuracy, we have revised our understanding of the combination rules for determining risk levels. Previously, our explanation might have been unclear or misleading to readers. To address this, we have included an excerpt from the CHEM21 solvent guide below, which provides a clear list of solvent risk levels and their ranking rules (Tables 1 and 2). (Table presented.) (Table presented.) CHEM21 solvent guide of "classical" solvents1 Ranking by default1 These two tables clearly illustrate the risk levels and comprehensive evaluation criteria for the solvents discussed in our article. To enhance reader understanding, we have also integrated this information into the corrected Fig. 1a, providing a visual representation of the risk levels associated with different solvents. Additionally, we have made two necessary revisions to the second paragraph of the article. The sentence "To address this challenge, the evaluation criteria outlined by CHEM21 offer a guide, categorizing solvents into four groups based on their impact on safety, health and environment10, namely recommended (no chemical incompatibility under process conditions), problematic (suitable for lab or kilo-scale lab use), hazardous (strong constraints on scale-up) and highly hazardous (solvents to be avoided even in the lab)" has been corrected to "To address this challenge, the evaluation criteria outlined by CHEM21 offer a guide, comprehensively categorizing solvents into three groups based on the

Recent advances in lithium-ion batteries have revealed the potential of Li-excess cation-disordered rock salt (DRX) cathodes, which expand the design space for cathode materials. The evidence of facile lattice substitution further provides a key strategy for activating redox reaction centers and enhancing the cycling performance of such materials. Here, the study explores how Sn-mediated local atomic ordering enhances reversible anionic redox activity in Li1.3Mn0.4Nb0.3O2 through the use of aberration-corrected scanning transmission electron microscopy, ex/in situ X-ray techniques, and theoretical calculation. The results demonstrate that Sn incorporation optimizes the local atomic structure, fostering the formation of rapid Li+ diffusion "elevator" pathways and short-range ordered structures, thereby enhancing the Li+ transport network. Additionally, quantitative analysis of the redox pathways and degree of participation for Mn and O during charge–discharge cycles reveals that the Sn-mediated electrode exhibits enhanced anionic O redox activity at high charging voltages, maintaining elevated activity throughout subsequent cycling. This sustained performance not only indicates increased redox capabilities but also suggests improved structural stability. By elucidating the complex interplay between composition, local structure, and performance, this study advances the understanding of DRX materials and underscores the potential of strategic elemental substitution for optimizing disordered cathode materials in next-generation energy storage systems. © 2025 Wiley-VCH GmbH.
