Bandwidth-Controlled Insulator-Metal Transition and Correlated Metallic State in 5$d$ Transition Metal Oxides Sr${}_{n+1}$Ir${}_n$O${}_{3n+1}$ ($n$=1, 2, and $\infty$)

S. J. Moon, H. Jin, K. W. Kim +8

We investigated the electronic structures of the 5$d$ Ruddlesden-Popper series Sr${}_{n+1}$Ir${}_n$O${}_{3n+1}$ ($n$=1, 2, and $\infty$) using optical spectroscopy and first-principles…
