    Abstract: A method of forming a nano-structure (100') involves forming a multi-layered structure (10) including an oxidizable material layer (14) established on a substrate (12), and another oxidizable material layer (16) established on the oxidizable material layer (14). The oxidizable material layer (14) is an oxidizable material having an expansion coefficient, during oxidation, that is more 1. Anodizing the other oxidizable material layer (16) forms a porous anodic structure (16'), and anodizing the oxidizable material layer (14) forms a dense oxidized layer (14') and nano-pillars (20) which grow through the porous anodic structure (16') into pores (18) thereof. The porous structure (16') is selectively removed to expose the nano-pillars (20). A surface (I) between the dense oxidized layer (14') and a remaining portion of the oxidizable material layer (14) is anodized to consume a substantially cone-shaped portion (32) of the nano-pillars (20) to form cylindrical nano-pillars (20').
