Metallicity in Ultra-Thin Oxygen-Deficient SrTiO${}_3$ Thin Films

Purnima P. Balakrishnan, Urusa S. Alaan, Matthew T. Gray +1

We report on the observation of metallic behavior in thin films of oxygen-deficient SrTiO${}_3$ - down to 9 unit cells - when coherently strained on (001) SrTiO${}_3$ or DyScO${}_3$-buff…
