Current instability and diamagnetism in small-diameter carbon nanotubes
We investigate the electronic instabilities in carbon nanotubes of short radius, looking at the scaling behavior of the different correlations and charge stiffnesses at low energies. We show that the Luttinger liquid behavior breaks down in the undoped 3,3 nanotubes at low temperatures, due to the appearance of soft modes in the sector of current excitations. The phenomenology derived from this...
متن کاملDispersion and separation of small-diameter single-walled carbon nanotubes.
The dispersion of small-diameter single-walled carbon nanotubes (SWNTs) produced by the CoMoCAT method in tetrahydrofuran (THF) with the use of amine was studied. The absorption, photoluminescence, and Raman spectroscopies showed that the dispersion and centrifugation process leads to an effective separation of metallic SWNTs from semiconducting SWNTs. Since this method is simple and convenient...
متن کاملVertical array growth of small diameter single-walled carbon nanotubes.
A hot filament chemical vapor deposition method has been developed to grow vertical array single-walled carbon nanotubes (SWNTs). In this study, a hot filament (temperature greater than 2000 degrees C) was used to activate gas mixtures of hydrogen and carbon containing species at sub-atmospheric pressures. Silicon substrates decorated with islands of iron were directly inserted into a preheated...
متن کاملDiameter-Controlled Synthesis of Carbon Nanotubes
Nearly monodisperse iron nanoclusters have been used to define the diameters of carbon nanotubes grown by chemical vapor deposition (CVD). Iron nanoparticles with average diameters of 3, 9, and 13 nm were used to grow carbon nanotubes with average diameters of 3, 7, and 12 nm, respectively. Transmission electron microscopy studies of the nanotubes show that the as-grown nanotubes are single-wal...
متن کاملTwist instability in strongly correlated carbon nanotubes.
We show that strong Luttinger correlations of the electron liquid in armchair carbon nanotubes significantly enhance the onset temperature of the putative twist Peierls instability and lead to its 1/R3 dependence on the tube radius. Depending on the values of the coupling constants the umklapp processes can either assist or compete with the twist instability. In the case of a competition the um...
