Abstract

This thesis explores

interfacial conductance and electric field-effects in LaAlO3/SrTiO3

heterostructures. High quality epitaxial LaAlO3 films were grown on SrTiO3

substrates by 90° off-axis sputter deposition. The conductance properties of the interfaces were modulated by applying external electric fields in different geometries, namely back-gating (applying an electric field to the back side of the substrate) and ionic liquid gating (which applies an electric field on the side of the LaAlO3).
