Considering the parameters of the WEIN2k software for simulation, all computations have been carried out using the PBE-GGA and TB-mBJ potential. Here, the impact of different M_x dopants (M_x = Cr and V) has been noticed, particularly in terms of band gap tuning. Structural and mechanical parameters show structural and thermodynamic stability and a notable decrease in bulk modulus as dopant changes from Cr to V, which improves electrical conductivity. Furthermore, the Pugh and Poisson ratio values depicts that all the examined composites are ductile in nature. The calculated TDOS and band structure outcomes reveal that the band-gap of 3.20, 1.21, and 1.06 eV has been found for pristine TbScO₃, TbSc_1-xCr_xO₃, and TbSc_1-xV_xO₃, employing TB-mBJ potential respectively. The reduction in band-gap is because of conducting filaments (CF) that develop in the RRAM gadget’s functional layer. The PDOS results reflect the formation of V.B. and C.B. is due to hybridization of Sc-<i>3d</i>, O-<i>2p</i>, Cr-<i>3d</i>, and V-<i>3d</i> states, oblique with minimum partaking of Tb-<i>6s</i> orbitals. The calculated optical parameters reveal that TbSc_1-xV_xO₃ shows 365 nm–12.4 μm (UV-IR) broad range absorption, which makes it a better option for photo influencing going forward, particularly in infrared (IR) RRAM gadgets.</p></div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"53 4","pages":"496 - 506"},"PeriodicalIF":2.6,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148061013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
