Superconductivity in the vicinity of a ferroelectric quantum phase transition

S. E. Rowley, C. Enderlein, J. Ferreira de Oliveira +4

Superconductivity has been observed in doped SrTiO${}_3$ at charge-carrier densities below 10${}^{18}$ cm${}^{-3}$, where the density of states at the Fermi level of the itinerant electr…
