Here, using first-principles density functional theory (DFT) calculations, we investigate the microscopic origin of the 2DEG formed at the interface between the band insulator KTaO$_3$ (KTO) and the Mott insulator LaVO$_3$ (LVO). Although both constituents are insulating in bulk, the LVO/KTO heterostructure develops robust metallicity at the interface, consistent with experimental observations.
