Embodiments of an electronic apparatus and embodiments for methods of forming the electronic apparatus include a conductive layer having an iridium-based layer, where the conductive layer is disposed on a dielectric layer containing zirconium oxide. In various embodiments, each of the zirconium oxide layer and the iridium-based layer may be structured as one or more monolayers. In various embodiments, each of the iridium-based layer and the zirconium oxide layer may be formed using atomic layer deposition.
