In this thesis, I will summarize my work on mesoscale devices created at the hetero interface between complex oxides lanthanum aluminate and strontium titanate (LaAlO3/SrTiO3). In chapter I, the relevant advances in the field of SrTiO3 as well as LaAlO3/SrTiO3 is reviewed. In chapter II, I will briefly describe relevant experimental setups and techniques, from transport at milliKelvin (mK) temperatures to our efforts on mK scanning probe and mK optical characterization of the system. In chapter III, I will summarize our observation of 1D nature of the superconductivity at LaAlO3 /SrTiO3. In chapter IV, results from 1D zigzag superconducting nanowires are summarized. In chapter V, I will summarize our simulation work on phase field modeling SrTiO3, followed by future works and outlook for this field in chapter VI.
