Magnetically Mediated Transparent Conductors: In${}_2$O${}_3$ doped with Mo

Abstract

First-principles band structure investigations of the electronic, optical and magnetic properties of Mo-doped In${}_2$O${}_3$ reveal the vital role of magnetic interactions in determining both the electrical conductivity and the Burstein-Moss shift which governs optical absorption. We demonstrate the advantages of the transition metal doping which results in smaller effective mass, larger fundamental band gap and better overall optical transmission in the visible -- as compared to commercial Sn-doped In${}_2$O${}_3$. Similar behavior is expected upon doping with other transition metals opening up an avenue for the family of efficient transparent conductors mediated by magnetic interactions.
