Direct Oxidation Growth of CuO Nanowires from Copper-Containing Substrates
Figure 1
Bright field TEM (a) and HRTEM (b) images of a nanowire grown from
a high-purity Cu foil with the inset of
(a) being a SAED pattern; (c) BF TEM image of
a nanowire grown from a low-purity
Cu gasket; and (d) HRTEM image of a
nanowire (the inset) shows fringes that are not parallel to
the nanowire axis.
