Angle-resolved photoemission spectroscopy studies on Rh-doped Sr2IrO4

ORAL

Abstract

Doped Mott insulator feature a plethora of rich physics, most of which remain unclear, owing to strong correlation between electrons therein. Sr2IrO4, a spin-orbit coupled Mott insulator, is a prominent candidate to host such emergent phenomena, especially, similar to those in cuprate high-temperature superconductors. Therefore, it is worthwhile to study a phase diagram of Sr2IrO4 as a function of dopant density to unveil possible instabilities or exotic phases. To this end, we performed angle-resolved photoemission spectroscopy (ARPES) studies on hole-doped Sr2IrO4, achieved by ionic substitution of Rh for Ir, due to the relatively weak spin-orbit coupling of Rh. Obtained ARPES spectra and related phenomena will be discussed in terms of the phase diagram.
