Charge transport in oxygen-deficient EuTiO${}_3$: the emerging picture of dilute metallicity in quantum-paraelectric perovskite oxides

Johannes Engelmayer, Xiao Lin, Christoph P. Grams +5

We report on a study of charge transport in EuTiO${}_{3-\delta }$ single crystals with carrier density tuned across several orders of magnitude. Comparing this system with other quasi-cubi…
