Abstract We performed polarized reflection and transmission measurements on the layered conducting oxide PdCoO2 thin films. For the a b-plane, an optical peak near Ω ≈ 750 cm−1 drives the scattering rate 1/τ(ω) and effective mass m *(ω) of th

Abstract We report on optical spectroscopic study of the Sr3(Ir1-x Ru x )2O7 system over a wide doping regime. We find that the changes in the electronic structure occur in the limited range of the concentration of Ru ions where the insulator–metal

Applications of correlated vanadium dioxides VO2(A) and VO2(B) in electrical devices are limited due to the lack of effective methods for tuning their fundamental properties. We find that the resistivity of VO2(A) and VO2(B) is widely tunable by dopi
