One Dimensional Transport in Carbon Nanotubes
The devices used in these studies consist of individual single-walled nanotubes (SWNTs) or SWNT ropes[9] to which electrical contacts are made, as shown in Figure 1. The nanotubes are deposited onto 2302 grown on top of a degenerately doped Si wafer. Atomic force microscope (AFM) imaging reveals that the diameters of the deposited objects vary between 1 and 10 nm, with the smallest ones being s...
متن کاملA Continuum Model For Stone-wales Defected Carbon Nanotubes
In this paper, a continuum model is proposed so that a Stone-Wales (SW) defected carbon nanotube (CNT) is replaced by an initial circumferential crack in a continuum cylindrical shell. For this purpose, the critical energy release rate and then the fracture toughness of a defected CNT are calculated using the results of an existing atomistic-based continuum finite element simulation. Finally, t...
متن کاملGiant thermopower in carbon nanotubes: A one-dimensional Kondo system
The electrical transport properties of single-wall carbon nanotubes are shown to be strongly influenced by the presence of transition-metal impurities derived from the catalyst introduced to stimulate their growth. Data on thermoelectric power and electrical resistance in the temperature range 10–400 K were obtained on a series of samples prepared using M -Y catalysts ~M5Cr, Mn, Co, Fe, Ni!. Th...
متن کاملThe One-Dimensional Wigner Crystal in Carbon Nanotubes
Electron-electron interactions strongly affect the behavior of low-dimensional systems. In one dimension (1D), arbitrarily weak interactions qualitatively alter the ground state producing a Luttinger liquid (LL)1 which has now been observed in a number of experimental systems2–6. Interactions are even more important at low carrier density, and in the limit when the long-ranged Coulomb potential...
متن کاملOne-dimensional silver nanostructures on single-wall carbon nanotubes
We report the synthesis and characterization of one-dimensional silver nanostructures using single-wall carbon nanotubes (SWCNT) as a template material. Transmission electron microscopy and scanning tunneling microscopy are consistent with the formation of a one-dimensional array of silver particles on SWCNT. We observe evidence for the excitation of the longitudinal silver plasmon mode in the ...
