Fabrication of tantalum-based nanodot arrays using AAO processing.a Schematic representation of fabrication procedure.b SEM images of the fabricated nanodot arrays.c AFM images of the fabricated nanodot arrays. Images are arranged from left to right: unprocessed silicon (Si), 10-nm nanodot array (10 nm), 50-nm nanodot array (50 nm), 100-nm nanodot array (100 nm), and 200-nm nanodot array (200 nm)
