Carbon nanotube graphoepitaxy: highly oriented growth by faceted nanosteps.
نویسندگان
چکیده
Single-wall carbon nanotubes grow along self-assembled nanosteps of annealed miscut C-plane sapphire. Depending on the miscut orientation and annealing conditions, graphoepitaxy leads to the formation of either unprecedentedly straight and parallel nanotubes, with angular deviations as small as +/-0.5 degrees , or to wavy nanotubes loosely conformal to sawtooth-shaped faceted nanosteps.

Orthogonal self-assembly of carbon nanotube crossbar architectures by simultaneous graphoepitaxy and field-directed growth.
Crossbar arrays of single-wall carbon nanotubes are produced spontaneously in a single step of chemical vapor deposition by simultaneous graphoepitaxy along faceted nanosteps and field-directed growth, perpendicular to each other. The two alignment mechanisms take place selectively on miscut C-plane sapphire and patterned amorphous SiO2 islands, respectively, without mutual interference, produc...
متن کاملDrawing Circuits with Carbon Nanotubes: Scratch-Induced Graphoepitaxial Growth of Carbon Nanotubes on Amorphous Silicon Oxide Substrates
Controlling the orientations of nanomaterials on arbitrary substrates is crucial for the development of practical applications based on such materials. The aligned epitaxial growth of single-walled carbon nanotubes (SWNTs) on specific crystallographic planes in single crystalline sapphire or quartz has been demonstrated; however, these substrates are unsuitable for large scale electronic device...
متن کاملCatalytically active nickel ˆ110‰ surfaces in growth of carbon tubular structures
Recent interest in the growth of aligned carbon nanotube films using transition metal catalysts has led to questions concerning the growth mechanism involved. In our experiment carbon tubules grown using Ni catalysts exhibit a preferred orientation relative to the catalytically active surfaces of Ni. The axial directions of the tubular structure are mainly parallel to the ^110& and ^042& direct...
متن کاملLiquid-crystalline processing of highly oriented carbon nanotube arrays for thin-film transistors.
We introduce a simple solution-based method for the fabrication of highly oriented carbon nanotube (CNT) arrays to be used for thin-film transistors. We exploit the liquid-crystalline behavior of a CNT solution near the receding contact line during tilted-drop casting and produced long-range nematic-like ordering of carbon nanotube stripes caused by confined micropatterned geometry. We further ...
متن کاملHighly aligned carbon nanotube forests coated by superconducting NbC.
The formation of carbon nanotube and superconductor composites makes it possible to produce new and/or improved functionalities that the individual material does not possess. Here we show that coating carbon nanotube forests with superconducting niobium carbide (NbC) does not destroy the microstructure of the nanotubes. NbC also shows much improved superconducting properties such as a higher ir...
