Ballistic resistance capacity of carbon nanotubes
Carbon nanotubes have high strength, light weight and excellent energy absorption capacity and therefore have great potential applications in making antiballistic materials. By examining the ballistic impact and bouncing-back processes on carbon nanotubes, this investigation shows that nanotubes with large radii withstand higher bullet speeds and the ballistic resistance is the highest when the...
متن کاملMultichannel ballistic transport in multiwall carbon nanotubes.
The electric transport properties of an individual vertical multiwall carbon nanotube (MWCNT) were studied in situ at room temperature in a scanning electron microscope chamber. It was found that the single MWCNT has a large current-carrying capacity, and the maximum current can reach 7.27 mA. At the same time, a very low resistance of about 34.4 ohms and a high conductance of about (460-490)G0...
متن کاملDiffusive-Ballistic Heat Conduction of Carbon Nanotubes and Nanographene Ribbons
Investigations of diffusive-ballistic heat conduction of finite-length single-walled carbon nanotubes and nanographene ribbons at room temperature have been carried out by using nonequilibrium molecular dynamics simulations. The length dependences of thermal conductivity reveal the variation of the balance between ballistic and diffusive heat conduction. For both systems, the profile indicates ...
متن کاملMultiwalled carbon nanotubes are ballistic conductors at room temperature
Following the experiments of Frank et al. [1], which demonstrated quantum transport in multiwalled carbon nanotubes, there have been several experiments that appear to contradict the main conclusion of that paper, which is that the transport of a MWNT at room temperature is ballistic. Here we demonstrate that the intrinsic resistance of cleanarc-produced carbon nanotubes is at most 200Ω/μm, whi...
متن کاملBallistic conductance in quantum devices: from organic polymers to nanotubes
With the size of electronic devices approaching the nanometer scale, transition to self-assembly in molecular electronics systems appears to be technologically the next step to pursue. Quantum conductors with an especially high potential for applications are organic polymers and carbon nanotubes. The latter are being considered for use as both nonlinear electronic devices and as connectors betw...
