According to the embodiments provided herein, a method for sputtering a TCO material onto a substrate includes process conditions that produce a textured topography at the interfaces of various layers. The textured topography can include an average roughness from about 5 to about 40 nm. The process conditions can include providing oxygen in the sputtering environment at a flow rate of from 0 to about 30 sccm; or heating the substrate to at least 200; or increasing the magnetic field strength to above 40 mT. The textured topography creates interfacial transition areas which have hybrid physical properties compared to their constituent materials.

Process for forming a coated article by (a) depositing a layer of an omega functionalized organophosphorous compound on an oxide substrate; (b) heating the substrate of step (a) to a temperature sufficient to bond the omega functionalized organophosphorous compound to the oxide substrate; (c) depositing a separate layer onto the layer produced by step (b); and (d) bonding the layers produced by steps (b) and (c) through the omega functional group.
