Conductance and gating effects at sputtered oxide interfaces

Yin, C. (2019)

Doctoral Thesis

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).
