Direct imaging of the coexistence of ferromagnetism and superconductivity at the LaAlO3/SrTiO3 interface
J. A. Bert, B. Kalisky, C. Bell +4
LaAlO3 and SrTiO3 are insulating, nonmagnetic oxides, yet the interface between them exhibits a two-dimensional electron system with high electron mobility,1 superconductivity at l…
Intrinsic spin-orbit coupling in superconducting δ-doped SrTiO3 heterostructures
M. Kim, Y. Kozuka, C. Bell +2
We report the violation of the Pauli limit due to intrinsic spin-orbit coupling in SrTiO3 heterostructures. Via selective doping down to a few nanometers, a two-dimensional superco…
Control of electronic conduction at an oxide heterointerface using surface polar adsorbates
Yanwu Xie, Yasuyuki Hikita, Christopher Bell +1
The transfer of electrons between a solid surface and adsorbed atomic or molecular species is fundamental in natural and synthetic processes, being at the heart of most catalytic r…
Fermi surface and superconductivity in low-density high-mobility δ-doped SrTiO3
M. Kim, C. Bell, Y. Kozuka +3
The electronic structure of low-density n-type SrTiO3 delta-doped heterostructures is investigated by angular dependent Shubnikov-de Haas oscillations. In addition to a controllabl…
