Revealing electron correlation effects in SrVO3 in the ultraclean limit

ORAL

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 (hMBE), 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.
