Charge transfer energy in iridates: a hard x-ray photoelectron spectroscopy study

D. Takegami, D. Kasinathan, K. K. Wolff +20

We have investigated the electronic structure of iridates in the double perovskite crystal structure containing either Ir${}^{4+}$ or Ir${}^{5+}$ using hard x-ray photoelectron spectro…
