Abstract: | InSb nanostructures have been synthesized by the use of
gas aggregation process. Nanoparticles with different shapes are obtained by
controlling the growth and deposition temperature of the InSb nanoclusters.
Triangular nanocrystals are commonly observed when the clusters are
extracted from the condensation chamber of the source and deposited on the
room temperature substrate at high vacuum. When the deposition is performed
inside the condensation chamber at high temperature near the melting point
of bulk InSb, nanoparticles formed on the substrate surface show several
kinds of 3-dimensional morphologies, such as triangular or rectangular
prisms, as well as hexagonal tablets. Keeping the same conditions for the
cluster source operation and deposition, after long time growth, nanorods
with hexagonal and quadrangular cross sections are formed through
vapor-liquid-solid (VLS) process. The origin of the difference on the
morphologies and shapes of the nanostructures is attributed to the
anisotropic growth of InSb, which is temperature dependent. |
