abstract = {To control the morphologies of one-dimensional (1D)
nanostructures, especially during the catalyst-assisted
growth of semiconductor nanostructures, is the key to unlock
their potential applications. In this work, we demonstrate
that, the morphology of the 1D silicon carbide (SiC)
nanostructures can be controlled by manipulating the
composition of the catalyst in the microwave plasma chemical
vapor deposition process. It is revealed that iron silicide
presents as the main catalyst to initiate the growth of 1D
SiC nanostructure. High-resolution transmission electron
microscopic analysis shows that, the stoichiometry of the
iron silicide governs the final morphology of 1D SiC
nanowire. For the growth of SiC nanowires, the catalyst is
Fe5Si3, while it is Fe3Si for SiC nanoneedles. A special
orientation match between the iron silicide catalyst and the
SiC nanowire is observed for the first time during the
growth of SiC nanostructures. The mechanism for the
different morphology of the SiC nanostructures is believed
to be the different etching resistivity of the catalyst
particles under H2 plasma etching. Based on the above
mechanism, a continuous change in the morphology of the SiC
nanostructures has been achieved by controlling the supply
of Si during growth.},
