Here, SLS mechanism catalyzed growth of nanowires is used
to create an additional control over the resulting morphology
from thermal decomposition of metal bis(diethylthiocarbamate)s
on substrates. Use of SLS nanowire formation from a thermally
evaporated catalyst layer has been demonstrated previously to
form nanowires directly on substrates.26 First we evaporate
a chromium sticking layer (2 nm) followed by a bismuth catalyst
thin film (12 nm) via thermal evaporation onto silicon substrates.
Then thermal decomposition of either Cu(II)[S2CNC4H10]2 or
Pb(II)[S2CNC4H10]2 in the presence of the melted Bi catalyst
results in the 1-D growth of Cu2S and PbS nanowires respectively
