Fabrication of nanorods by metal evaporation inside the pores of ultra-thin porous alumina templates
(2007)Porous alumina has attracted a great deal of attention as a template material for the growth of nanowires and nanodots. Typically, the pores have a high aspect ratio, which forbids the use of evaporation techniques for ...
