Ab initio investigation of electronic structure and optical properties of IrSn(4)
We have examined the electronic structure and optical properties of intermetallic IrSn(4) for three polymorphic modifications, α-IrSn(4), β-IrSn(4), and γ-IrSn(4), utilizing the first-principles PAW-PBEsol-GGA and FP-LAPW-LSDA methods. The obtained electronic structure data reveal clear-cut differen...

Sumario: | We have examined the electronic structure and optical properties of intermetallic IrSn(4) for three polymorphic modifications, α-IrSn(4), β-IrSn(4), and γ-IrSn(4), utilizing the first-principles PAW-PBEsol-GGA and FP-LAPW-LSDA methods. The obtained electronic structure data reveal clear-cut differences between α-IrSn(4) and the remaining morphs. This observation may be used to explain the appearance of superconductivity in β-IrSn(4), and also provides reasonable grounds to suspect eventual superconductivity in γ-IrSn(4). Therefore, it is highly desirable to carry out extended measurements on γ-IrSn(4) at lower temperatures. |
