This significantly restricts the application scope of MoS<sub>2</sub>. Therefore, modifying MoS<sub>2</sub> to enhance its frictional performance in humid conditions is of great necessity. To this end, MoS<sub>x</sub>-Y composite coatings with varying yttrium contents were fabricated by direct current magnetron sputtering. The effects of Y doping and its concentration on the structural characteristics, mechanical properties, and tribological performance of MoS<sub>x</sub> coatings were systematically investigated using SEM, XPS, XRD, nanoindentation, and friction tests. The results indicate that the doped Y element mainly existed in the form of Y<sub>2</sub>O<sub>3</sub> within the coating. As the Y element content increased, the hardness and elastic modulus of the MoS<sub>x</sub>-Y composite coating gradually increased. The tribological properties of the coatings with different Y contents under a humid atmosphere (RH=60 %) were comprehensively evaluated through rotary friction experiments. The experimental results reveal that the introduction of appropriate Y contents can effectively reduce the friction coefficient of the MoS<sub>x</sub> coating in a humid environment to approximately 0.1, and significantly enhance its friction life. The doping of the Y element inhibits the growth of the (100) and (110) planes of MoS<sub>x</sub>, causing the coating to grow preferentially along the (002) plane, which is an important factor contributing to the enhancement of the tribological properties of the MoS<sub>x</sub> coating by yttrium doping.

This review examines computational simulation approaches that address these challenges through atomistic and quantum mechanical methods. Significant progress has been achieved using Fukui function analysis for additive screening, density functional theory (DFT) for surface passivation mechanisms, and molecular dynamics (MD) simulations for CMP processes. These simulation approaches have generated quantitative insights into key CMP metrics: surface roughness reduction from ∼5 nm to sub-1 nm scales, material removal rates ranging from 100 to 1000 Å/min depending on slurry chemistry, and subsurface damage layer thickness characterization. Mechanistically, simulations reveal three primary pathways: chemical dissolution through surface oxidation, mechanical abrasion via particle-surface interactions, and synergistic tribochemical reactions combining both effects. DFT calculations elucidate electronic structure-property relationships governing selectivity between different materials, while MD simulations capture real-time surface evolution and particle dynamics. Reactive force field methods bridge quantum mechanical accuracy with classical simulation timescales, enabling comprehensive mechanistic understanding across multiple length scales. Future research directions include development of machine learning-accelerated simulations, integration of multiphysics models connecting molecular-scale phenomena to wafer-scale uniformity, and predictive frameworks for novel slurry chemistries. Enhanced computational methods targeting industrial-scale process optimization and real-time process control represent critical advancement opportunities for next-generation CMP technology development.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"29 ","pages":"Article 100819"},"PeriodicalIF":8.7,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144864193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several researchers use ultra-thin adhesive metallic layers, such as Ti, Cr, or Ni; while this method effectively enhances adhesion, all these metals are oxygen scavengers (in more or less degree) and they significantly alter the charge transport. Here we present a fabrication process for 2D-materials-based electronic devices that leads to high yield without the need of using adhesive metallic layers. Our method consists on using a discontinuous coverage of the 2D material during the photolithography step assisted by a negative photoresist, combined by electron beam evaporation of metal under moderate vacuum (5 × 10<sup>−6</sup> Torr) to produce a truly van der Waals interface and avoid damaging the 2D material. When using this improved method, we systematically achieve defect-free Au/hBN interfaces with good adhesion, which lead to 100 % fabrication yield (340 devices were fabricated correctly). Electrical characterization reveals low leakage currents below 10 pA and minimal device-to-device variability, demonstrating the process’s effectiveness.

The results indicate that: In solid solution strengthening, at a Mo content of 12% (NiCoMo12), lattice distortion effectively inhibits dislocation slip, significantly improving the matrix strength. For grain boundary strengthening, at a Mo content of 30% (GB-30), the pinning effect of grain boundaries is markedly enhanced, with the most uniform local stress distribution and the smallest shear strain regions, demonstrating optimal strengthening performance. Additionally, increasing Mo content accelerates the FCC → HCP phase transformation, but an appropriate Mo concentration effectively suppresses this transformation, maintaining the stability of the crystal structure.
