The optimized structure is confirmed to be dynamically and mechanically stable, exhibiting isotropic elastic behavior with an elastic modulus of 18.92 N/m and a shear modulus of 7.56 N/m. Electronic band structure analysis reveals that the <em>γ</em>-SnTe monolayer is an indirect semiconductor with a band gap of 2.56 eV, and the separation between charge carriers is clearly observed, with an effective mass mobility of approximately 0.44 <em>m₀</em>. Under biaxial strain, the band states continuously shift, optimizing redox potentials for surface chemical reactions. The material also demonstrates high piezoelectric coefficients, enabling efficient conversion of mechanical energy into electrical energy. Additionally, ferroelectricity is confirmed with a residual polarization of <em>P_z</em> = 5 pC/m and a low-energy switching barrier, making <em>γ</em>-SnTe highly suitable for low-power memory devices. These findings establish the <em>γ</em>-SnTe monolayer as a promising multifunctional material with potential applications in green energy technologies, electromechanical systems, and next-generation memory devices.</div></div>","PeriodicalId":10650,"journal":{"name":"Computational Materials Science","volume":"253 ","pages":"Article 113879"},"PeriodicalIF":3.1,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the effect of post-weld heat treatment on the formability of aluminum alloy 6061 and SAE1020 mild steel tailor welded blanks fabricated by friction stir welding was evaluated using limiting dome height test. It was found that the specimens which underwent post-weld heat treatment recorded a lower springback and higher value of plane strain, indicating a better formability.
