Large orbital polarization in nickelate-cuprate heterostructures by dimensional control of oxygen coordination

In correlated materials, physical properties depend on orbital occupancy and polarization. Here, a way to control the oxygen coordination via dimensionality of superlattices is presented that results in the change of orbital occupancy by 30%, which is larger than what has been achieved by other meth...
