Ultrathin open-ended porous TiO2 membranes for surface nanopatterning in fabricating nanodot arrays†
Abstract
This communication reports an approach to fabricate large-scale ultrathin open-ended porous TiO2 membranes (UOP-TMs) with ordered straight-through pores. Bi nanodot arrays on Si substrates are obtained by using the UOP-TMs as surface patterning masks.
