Electronic band sculpted by oxygen vacancies and indispensable for dilute superconductivity

Electronic band sculpted by oxygen vacancies and indispensable for dilute superconductivity

Dilute superconductivity survives in bulk strontium titanate when the Fermi temperature falls well below the Debye temperature. Here, we show that the onset of the superconducting dome is dopant dependent. When mobile electrons are introduced by removing oxygen atoms, the superconducting transition...
