Preparation of macroscopic two-dimensional ordered array of indium nanodots

Abstract
A macroscopic two-dimensional highly ordered array of indium nanodots was achieved using a very simple method of vacuum evaporation on anodic aluminum. The ordered indium nanodots, seated on small, shallow holes of an Al template, are arranged in a rhombic pattern with a typical period of about 100 nm. The formation mechanism of the indium nanodots is discussed.
