摘要：

The quasi-two-dimensional electron gases formed at the interface between insulators such as SrTiO3/LaAlO3 are predicted to arise from an interfacial electronic reconstruction, but the extent to which oxygen vacancies within the substrate contribute to the conduction remains unclear. We show that delta-doping the interface with transition metal cations dramatically alters the properties and supports the model of a highly two-dimensional charge sheet.
