Electronic Structure near Metal-Insulator Transition in Sr$_{3-x}$La$_{x}$Ir$_{2}$O$_{7}$

ORAL

Abstract

The bilayer perovskite iridate Sr$_3$Ir$_2$O$_7$ exhibits an insulating state at low temperature driven by the cooperation of spin-orbit coupling and moderate Coulomb correlations. Transport measurements have shown a metal-insulator transition with electron doping in Sr$_{3-x}$La$_{x}$Ir$_{2}$O$_{7}$ near x = 0.12. We will show how the electronic structure evolves through the metal to insulator transition and discuss these results in terms of strong correlations and how these evolve with doping.
