  The discovery of a two-dimensional (2D) electron gas at the (110)-oriented
LaAlO3/SrTiO3 in- terface provided us with the opportunity to probe the effect
of crystallographic orientation and the ensuing electronic reconstructions on
interface properties beyond the conventional (001)-orientation. At temperatures
below 200 mK, we have measured 2D superconductivity with a spatial extension
significantly larger (d approx. 24 - 30 nm) than previously reported for
(001)-oriented LaAlO3/SrTiO3 interfaces (d approx. 10 nm). The more extended
superconductivity brings about the absence of violation of the Pauli
paramagnetic limit for the upper critical fields, signaling the distinctive
nature of the electronic structure of the (110)-oriented interface with respect
to their (001)-counterparts
