ABSTRACT
Nanowires and nanoholes are two kinds of typical nanostructures. Commonly, these nanostructures have cross-sectional dimensions (wires and holes) that can be tuned from a few nanometers to hundreds of nanometers, with lengths spanning from hundreds of nanometers to several micrometers. A large number of nanowires can be distributed on substrates to form nanowire arrays, and a mass of nanoholes can also be arranged in slabs to form nanohole arrays.
