Abstract

Two dimensional electron gases (EG) at the heterointerface of complex oxides show fascinating properties. The authors report on an EG formed at the CaHfO3/SrTiO3 interface independent of interface termination and robust against environmental conditions most likely originating from oxygen non-stoichiometry.
