主 题:density functional theory(DFT) effects of pressure electronic band structure optical properties
摘 要:We perform the first-principles investigations of the structural,elastic,electronic,and optical properties of SrBO3(B=Cr,Fe)perovskites under pressure based on density functional theory(DFT).This is the first detailed pressure-dependent study of the physical properties for these *** calculated structural parameters are consistent with the existing experimental results and slightly decrease with the application of *** mechanical properties are discussed in detail and reveal that the SrCrO3 is harder than *** pressure,these compounds behave like half-metals,confirmed by their band structure and density of *** the SrCrO3 retains its half-metallic nature under pressure,SrFeO3 becomes metallic for both up-spin and down-spin *** charge density and bond overlap population reveal the covalent nature of Cr–O bond and Fe–O bond in the studied *** optical properties of SrBO3,also discussed for the first time,reveal some interesting results.
