Development of multipurpose metal-oxide films with nanostructured tailored morphologies and tunable properties via anodic processing of A/Nb metal layers

Niobium oxide is now starting to replace tantalum oxide as a dielectric and solar-energy conversion cells since the oxide shows electrochromic and photoelectrochemical properties. In this work, we have synthesized ...
