Herein, employing first-principles calculations, we investigate the performance of sub-5 nm FETs based on the Janus MoSiGeN₄ material and reveal the role of intrinsic out-of-plane electric polarization. We demonstrate that the synergistic effect of the intrinsic polarization field and the external electric field enhances the performance of Janus MoSiGeN₄ FETs over MoSi₂N₄ and MoGe₂N₄ FETs. Our simulations show that a 3 nm gate-length cold-source Janus MoSiGeN₄ FET, utilizing LaOCl as the dielectric material and an appropriate underlap structure, fulfills the HP and LP standards set by the International Technology Roadmap for Semiconductors (ITRS), with a subthreshold swing approaching the Boltzmann tyranny of 60 mV/dec. Notably, the optimized 1 nm gate-length MoSiGeN₄ FET achieves an on-state current of 990 μΑ/μm (HP) and 690 μΑ/μm (LP), surpassing other theoretical two-dimensional FETs at the same gate length. Taking the defect effects into account, the MoSiGeN₄ FET maintains a high on-state current that surpasses the ITRS for HP and LP standards. Our results provide a promising approach for designing ultra-short channel FETs suitable for both HP and LP applications.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"28 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the insufficient thermodynamic potential of photogenerated carriers and the sluggish multi-proton coupled electron transfer (PCET) process severely hinder the formation of CH₄ and other hydrocarbons. Hence, we constructed an all-organic S-scheme heterojunction photocatalyst (CN/UPDI-<em>x</em>) with large π-delocalization via π-π interactions, with CO and CH₄ yields of 34.10 and 4.55 μmol g⁻¹ h⁻¹, where the CH₄ yields were 12.3 and 11.7 times higher than those of pristine CN and UPDI, respectively.

This work introduces Y₂O₃ nanoparticles into CuCr alloy by the laser powder bed fusion (LPBF) process, aiming to further enhance its mechanical properties while preserving its electrical conductivity. The spherical Cu-0.7Cr-2Y₂O₃ composite powders with excellent flowability are prepared using the spray drying and pre-sintering methods. Different laser powers and scanning speeds are utilized to optimize the LPBF forming processes. The CuCr-Y₂O₃ composites with a high relative density of 99.4% are successfully fabricated at a laser power of 250 W and a scanning speed of 400 mm/s. The effect of aging treatments on the evolution of the microstructure and properties of as-printed CuCr-Y₂O₃ composites is systematically analyzed. In the LPBF samples, Y₂O₃ particles with an average size of 46.7 nm are homogeneously dispersed in the copper matrix, and few Cr nano-precipitates are observed. Following aging treatment, the morphology and size of Y₂O₃ particles remain consistent, while a greater density of Cr phases, with an average size of 7.3 nm, precipitate and exhibit a coherent interface relationship with the matrix. Aging treatment conducted at 460°C for 1.5 h results in a peak tensile strength of 691.6 MPa, elongation of 21.5%, electrical conductivity reaching 79.6% IACS, microhardness values of 152.7 HV at room temperature and 112.2 HV at 500°C. Moreover, the conductivity mechanisms and strengthening mechanisms are discussed. The full aging of solid solution Cr elements and minimal negative effects of Y₂O₃ particles on electron scattering, contribute to the excellent electrical conductivity. The superior mechanical properties at both room and elevated temperatures are primarily attributed to the synergistic strengthening effect provided by the shearing mechanism of fine Cr precipitates and the Orowan mechanism of Y₂O₃ particles and lager Cr precipitates.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"163 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

N-PCS with <em>C</em>_ch from 150 nm to 3 μm is considered in this study. The fracture toughness (<em>K</em>_IC) of both SCS and N-PCS can be predicted from their intrinsic strengths and respective <em>C</em>_ch. Predicted <em>K</em>_IC values of 0.90–1.40 MPa √m for SCS and 1.56–5.31 MPa √m for N-PCS are confirmed by collected experimental data of 0.74–1.38 MPa √m for SCS and 1.43–3.46 MPa √m for N-PCS. The intrinsic relation between the <em>K</em>_IC, intrinsic strength and characteristic microstructure is both practically useful and fundamentally significant. The macroscopic <em>K</em>_IC and intrinsic strength, previously considered as two separate material properties, are now linked together by the atomic-/nano-scale microstructures.

However, inhomogeneous precipitation resulting from dislocation accumulation can significantly degrade the mechanical properties. In this study, an attempt was made to establish a correlation between creep stress, dislocation density and precipitation strengthening to address the degradation in plasticity. The results show that the application of creep stress does not significantly change the low-angle grain boundaries (LAGBs). The distinct microstructure of the T₁ phase and the disappearance of the precipitation-free zones (PFZs) at the grain boundaries (GBs) are the main factors responsible for the improved mechanical properties. The micro-elastic lattice strain induced by creep stress can effectively mitigate the depletion of dislocations by aging precipitation, and the nucleation kinetics of precipitates can be significantly enhanced. During the creep aging process under 150 MPa stress, the T₁ phase forms a sandwich structure via interstitial nucleation, with its number density increasing from 2.25 × 10¹⁴/m² to 4.04 × 10¹⁴/m². The dislocation density induced by creep stress also contributes to the narrowing or disappearance of the PFZs at the GBs, further improving the capacity for localized plastic deformation. Finally, the Al-Li alloy with excellent ultimate tensile strength (∼754.0 MPa), yield strength (∼718.1 MPa) and elongation (∼8.8%) was obtained.
