Abstract 

The experimental challenge to engineer multicomponent ABO3 perovskite oxides as atomic-scale thin films is to synthesize intrinsic defect-free materials. In this talk, I will focus on how the recently developed hybrid molecular beam epitaxy, which combines traditional elemental sources with metal-organic sources, opens an adsorption-controlled growth window, thus giving access to the cleanest complex oxide materials. In particular, I will discuss how temperature-dependent resistivity and Hall effect measurements on ultraclean samples of the classic example of a “simple” correlated metal, SrVO3, reveal anomalous anisotropic correlation effects at low temperature.
