In Situ TEM Observation of a Microcrucible Mechanism of Nanowire Growth

Nanowire Growth Observed In the hypothetical microcrucible growth mechanism for nanowires, a molten catalytic particle located in a pore on a substrate continually feeds the outward growth of the wire. To observe such a mechanism requires the ability to examine nanowire growth in situ. Boston et al. (p. 623 ) studied various stages of Y 2 BaCuO 5 nanowire growth using transmission electron microscopy and were able to observe a microcrucible growth mechanism directly.
