One way to induce insulator-to-metal transitions in the spin-orbit Mott insulator ${\mathrm{Sr}}_{2}\mathrm{Ir}{\mathrm{O}}_{4}$ is to substitute iridium with transition metals (Ru, Rh). However, this creates intriguing inhomogeneous metallic states,

With optical spectroscopy we provide evidence that the insulator-metal transition in ${\mathrm{Sr}}_{2}{\mathrm{Ir}}_{1\ensuremath{-}x}{\mathrm{Rh}}_{x}{\mathrm{O}}_{4}$ occurs close to a crossover from the Mott- to the Slater-type. The Mott gap at $

${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ is characterized by a large spin-orbit coupling, which gives rise to bands with strongly entangled spin and orbital characters, called ${\mathrm{J}}_{1/2}$ and ${\mathrm{J}}_{3/2}$. We use light-polarization depe

International audience; The crystallographic orientation of SrIrO3 surfaces is decisive for the occurrence of topological surface states. We show from density functional theory computations that (001) and (110) free surfaces have comparable energies,

Iridates are often viewed as an equivalent of cuprates with strong spin-orbit coupling. As such, they offer a new way to study the physics of Mott insulators. The hybridization with oxygen is, of course, essential in both compounds and may play a cru

In ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ and ${\mathrm{Sr}}_{3}{\mathrm{Ir}}_{2}{\mathrm{O}}_{7}$, correlations, magnetism, and spin-orbit coupling compete on similar energy scales, creating a new context to study metal-insulator transitions (MIT). W
