Hafnium-Oxide 3‑D Nanofilms via the Anodizing of Al/Hf Metal Layers [PDF]
, 2018 Hafnium-oxide films with self-organized nanostructured 3-D architectures and variable dimension (10 to 400 nm) are synthesized via the high-current anodizing of thin aluminum-on-hafnium layers in phosphoric, malonic, and oxalic acid electrolytes.
