“…There are also methods of nanowire growth that may be loosely classified as vapour solid (VS) growth. These often resemble chemical vapour deposition in that an element may be deposited from a compound gas, for example the growth of copper nanowires [33] from CuCl gas. VS is therefore often a reactive process.…”

Bismuth thin films of thickness in the region of 500 nm have been prepared by planar magnetron sputtering onto glass, silicon and GaAs substrates. Electron microscopy of these films reveals that bismuth whiskers grow spontaneously when the substrate is heated to temperatures between 110ºC and 140ºC during deposition and the optimum temperature for such growth is largely independent of substrate. Depositing films under similar conditions using thermal evaporation does not, however, produce the whisker growth. X-ray diffraction has been employed to investigate film texture with temperature and it has been shown that the and has a higher change-over temperature. The whiskers that grow from the film emerge at off-normal angles between 43.3º and 69.2º with a mean of 54±3º. The projected length of whiskers on a 500 nm film on a GaAs substrate shows a wide distribution to a maximum of more than 100 µm. The mean projected length for this sample was 16±1 µm and the diameter is around 0.5 µm. Measurements of the electrical properties of the whiskers at room temperature reveals ohmic behaviour with an estimated resistivity of 2.2±0.2 µΩm. Detailed examination of scanning electron micrographs, eliminates all growth mechanisms except tip growth by a non-catalysed vapour-solid/vapour-liquid-solid method. By depositing thinner films it is shown that this spontaneous growth of whiskers offers a route to fabricate high quality bismuth nanowires of lengths exceeding 10 µm.2

“…Because of the ease of surface oxidation, copper nanowires are often fabricated in vacuum by the use of chemical vapour deposition or thermal evaporation techniques at high temperature. [1][2][3] Alternatively, copper nanowires can also be electrochemically deposited on the step edges of substrates or into hard templates, [4][5][6][7][8][9][10][11][12][13][14] hydrothermally synthesized with carbon/ polymer coating in one-pot reactions, [15,16] or chemically prepared in aqueous solutions through chemical reduction of Cu II by strong reducing agents. [17][18][19][20][21][22][23] Herein, we describe copper nanowires chemically prepared in the organic phase through the controlled disproportionation of Cu I , which involves the initial dissolution of CuCl through coordination with oleylamine in organic solvent and the subsequent disproportionation of the Cu I complexes into metallic Cu 0 and bivalent Cu II at 200 8C.…”

A preceramic polymer route developed in 1975 has been simplified to efficiently generate β‐SiC nanostructures, including cubic cages (see Figure), cubic shells, and nanoparticles. The nanostructures are generated by the reaction of liquid sodium with the vapors of methylchlorosilanes, with the morphology of the resulting nanostructures dependent upon the interactions between the phase‐separated solid products generated at the interface of the vapor–liquid/solid reactions.
