Multishelled Gold Nanowires
نویسنده
چکیده
The current miniaturization of electronic devices raises many questions about the properties of various materials at nanometre-scales. Recent molecular dynamics computer simulations have shown that small finite nanowires of gold exist as multishelled structures of lasting stability. These classical simulations are based on a well-tested embedded atom potential. Molecular dynamics simulation studies of metallic nanowires should help in developing methods for their fabrication, such as electron-beam litography and scanning tunneling microscopy.

Molecular dynamics computer simulations which employ the embedded-atom potential show that nanowires of gold exist as multishelled structures. We simulate double-walled gold nanowires and calculate the capacitance of a finite nanometer-size cylindrical capacitor. For the sizes for which multishelled nanowires appear in simulations we find the capacitances below one attofarad. 1 Finite-size syst...
متن کاملGold catalytic Growth of Germanium Nanowires by chemical vapour deposition method
Germanium nanowires (GeNWs) were synthesized using chemical vapor deposition (CVD) based on vapor–liquid–solid (VLS) mechanism with Au nanoparticles as catalyst and germanium tetrachloride (GeCl4) as a precursor of germanium. Au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in Au colloidal s...
متن کاملInvestigation of Silicon Oxide (SiOx) Nanowires Growth with Gold/Chromium Catalysts
We report the growth of high density silicon Oxide (SiOx) nanowires at an elevated temperature. The nanowires density is enhanced by inserting a thin layer of chromium metal in gold/Si catalyst system. The SiOx nanowires were grown with gold/chromium catalysts stack layer on the Si substrate at different temperatures ranging from 1050oC to 1150oC. Under the catalysis reaction of the gold/chromi...
متن کاملUltrafast Optical Heating Induced Polarization-Dependent Optical Switching in Gold Nanowires
Excitation using femtosecond laser pulses induced ultrafast heating of discontinuous gold nanowires, resulting in transient thermal expansion of the gold nanostructures that constitute the nanowires. The cross-plasmon resulting from the closely arranged gold nanostructures along the nanowires was modified by the change in the small gaps due to the thermal effect. This led to the spectral shift ...
متن کاملGold nanowires and the effect of impurities
Metal nanowires and in particular gold nanowires have received a great deal of attention in the past few years. Experiments on gold nanowires have prompted theory and simulation to help answer questions posed by these studies. Here we present results of computer simulations for the formation, evolution and breaking of very thin Au nanowires. We also discuss the influence of contaminants, such a...
