Abstract: Abstract This paper compares the advantages of a catalyst-free vertically aligned coaxial titanium dioxide nanowire/germanium nanowire (TiO2-NW/Ge-NW) heterostructure compared to basic germanium nanowire (Ge-NW) on silicon (Si) substrate. Both were fabricated using the glancing angle… read more here.
