Electronic reconstruction at an interface between transition metal oxides in epitaxial heterostructures can give rise to new states of matter with completely new properties [1]. A prominent example of such electronic reconstruction is the two dimensional electron gas formed on the interface between two insulators LaAlO3 and SrTiO3. The main focus of this experimental PhD project will be studies of the interface and doping induced effects between perovskite oxides, e.g., antiferromagnetic La1-xSrxFeO3, and semiconducting or insulating oxides, e.g., SrTiO3 and LaAlO3. The project will combine growth methods (pulsed laser deposition) and analytical methods (e.g., magneto-transport, magnetometry, ellipsometry, XRD and AFM). [1] H.Y.
