TL;DR: The calculation of the electron spatial distribution in the confinement potential shows that the high-mobility electrons responsible for superconductivity set at the edge of the gas whose extension can be tuned by the field effect.

TL;DR: This work examines the magnetic-field-driven quantum phase transition that occurs in electrostatically gated superconducting LaTiO3/Sr TiO3 interfaces and shows that it belongs to the (2+1)D XY model universality class.

TL;DR: It is shown that the Fermi energy lies intrinsically near the top of the quantum well and beyond a filling threshold, electrons added by electrostatic gating escape from the well, hence limiting the possibility to reach a highly-doped regime.

TL;DR: In this article, the authors model intrapuddle superconductivity by a multiband system within a weak coupling BCS scheme, and derive microscopic parameters, extracted by fitting the transport data with a percolative model, yield a consistent description of the dependence of the average intrapudd critical temperature and superfluid density on the carrier density.

TL;DR: In this article, the two-dimensional electron gas formed at the interfaces of oxide heterostructures is investigated by means of a combined perturbation by near-ultraviolet radiation and an electrostatic field, applied both separately and simultaneously.
