Fabrication and characterization of metallic nanowires
نویسنده
چکیده
The shape of metallic constrictions of nanoscopic dimensions ~necks! formed using a scanning tunneling microscope is shown to depend on the fabrication procedure. Submitting the neck to repeated plastic deformation cycles makes it possible to obtain long necks or nanowires. Point-contact spectroscopy results show that these long necks are quite crystalline, indicating that the repeated cycles of plastic deformation act as a ‘‘mechanical annealing’’ of the neck. @S0163-1829~97!05227-2#

Characterization of DNA-Templated Metal Nanowires DNA molecules as templates for ultrathin metallic nanowires
Suspended molecules of DNA are used as substrates for deposition of various metals by DC sputtering. The result is the formation of metallic nanowires, most with diameters of 10-50 nm. Homogeneous wires have been observed when a proper metal is chosen. For the first time, these DNA-templated nanowires are fabricated on substrates conducive to transmission electron microscopy. TEM and SEM analys...
متن کاملFree-standing NiTi alloy nanowires fabricated by nanoskiving.
We report on free-standing NiTi alloy nanowires (120 nm × 75 nm) fabricated using a technique referred to as "nanoskiving", which complements conventional thin film sputter deposition with ultramicrotomy for thin sectioning. To date, the technique has been limited to pure metals without exploring metallic alloys. Leveraging the technique for the fabrication of shape memory alloy (SMA) nanostruc...
متن کاملNanowires 4 . Nanowires
This chapter provides an overview of recent research on inorganic nanowires, particularly metallic and semiconducting nanowires. Nanowires are one-dimensional, anisotropic structures, small in diameter, and large in surfaceto-volume ratio. Thus, their physical properties are different than those of structures of different scale and dimensionality. While the study of nanowires is particularly ch...
متن کاملElectrochemical fabrication of Cu/Pd multilayer nanowires in polycarbonate template
In this work,copper/palladium (Cu/Pd) multilayer nanowires were successfully prepared by electrodeposition method using polycarbonate template. The fabrication of Pd/Cu multilayer nanowires was controlled by analyzing the current–time transient during electrodeposition using potentiostat. The morphological properties of the nanowires were studied by scanning electron microscopy (SEM) and resu...
متن کاملSub-10 nanometre fabrication: molecular templating, electron-beam sculpting and crystallization of metallic nanowires
Homogeneous metallic nanowires with diameters below 10 nm are produced by sputter coating suspended DNA molecules and/or carbon nanotubes. A fabrication method is described that allows ‘e-beam nanosculpting’, i.e. local modification of the shape of nanowires, with a resolution of ∼3 nm. The process is performed with a focused electron beam (e-beam) in a transmission electron microscope, under d...
