Tunable one-dimensional electron gas carrier densities at nanostructured oxide interfaces
The emergence of two-dimensional metallic states at the LaAlO(3)/SrTiO(3) (LAO/STO) heterostructure interface is known to occur at a critical thickness of four LAO layers. This insulator to-metal transition can be explained through the “polar catastrophe” mechanism arising from the divergence of the...
