摘要：
Hexagrams were revealed on the barrier layer of porous anodic alumina during chemical etching and ion milling, indicating non-uniform etching. Six-membered ring structure holes appear firstly around the center of each cell and subsequently merge into a primary circular opening. A new pore-opening mechanism is proposed, and the possible origin of the non-uniform etching rate is also discussed. (C) 2015 Elsevier B.V. All rights reserved.
