| Description |
Silver nanowires show enhancement in desired
properties, due to high surface area and high aspect ratio, which
increases the possibility in design and development of many
advanced optoelectronic devices. The organization of silver atoms
and the morphology of cylindrical nanowire highly influence the
desired properties at various physical conditions during
applications. Therefore, the synthesis of nanowires with desired
atomic organization becomes essential. In the present study, a
pseudo-1D morphology of silver nanowires, encapsulated into a
Single Wall Carbon Nanotubes (SWCNTs), has been investigated by employing Molecular Dynamics (MD) simulation. At
high temperature (T = 1500 K), molten silver encapsulated into a
SWCNT attaining a low energy state followed by restricted
thermal motion or vibration. With an increase in SWCNT
diameter, various unique pseudo-1D morphologies of encapsulated silver atoms were observed during cooling from 1500 to 10 K.
Silver atoms, encapsulated into a SWCNT having a diameter of 10.85 Å, mainly reveal 5-fold symmetrical icosahedral (ico)
having pseudo-1D morphology. With a further increase in diameter (d = 40.68 Å) of SWCNT, a decagonal pattern consisting of
face centered cubic (fcc), hexagonal closed packed (hcp) and body centered cubic (bcc) was evolved due to nonhomogenous
packing of silver atoms into SWCNT. Simulation results indicate that the diameter of SWCNT is the one of the major factors
controlling the pseudo-1D morphology of silver nanowire. The present theoretical investigations provide a guideline and enhance
the current understanding related to solid state physical phenomena of metal nanowires synthesis.
