High-density Two-Dimensional Small Polaron Gas in a Delta-Doped Mott Insulator
High-density Two-Dimensional Small Polaron Gas in a Delta-Doped Mott Insulator
Heterointerfaces in complex oxide systems open new arenas in which to test models of strongly correlated material, explore the role of dimensionality in metal-insulator-transitions (MITs) and small polaron formation. Close to the quantum critical point Mott MITs depend on band filling controlled by random disordered substitutional doping. Delta-doped Mott insulators …
