Crystals of covalently bonded carbon nanotubes: Energetics and electronic structures
Structure and stability of hexagonally polymerized carbon nanotube solids are investigated using a generalized tight-binding molecular-dynamics scheme. The stable structures show internanotube connectivity via the 212 and 214 cycloaddition process. Calculated electronic density of states indicates that the studied materials have semiconducting or insulating properties depending on the type of i...
متن کاملSurface functional groups of carbon nanotubes to manipulate capacitive behaviors.
The covalent functionalization of carbon nanotubes (CNTs) is a basic but important chemistry that can modify their physicochemical properties, resolve their poor dispersion capability, and improve their capacitance to enable their use as high-energy supercapacitors. However, the relationship between functional groups on the CNT surface and their capacitive characteristics has not yet been explo...
متن کاملINFLUENCE OF SURFACE FUNCTIONAL GROUPS ON MOLECULAR ADSORPTION BY SINGLE WALLED CARBON NANOTUBES (SWNTs)
Experimental A stainless steel ultra high vacuum (UHV) chamber, pumped by a turbo molecular pump backed by a mechanical pump, providing a base pressure of 5X10 torr after bake out, was used for temperature programmed desorption (TPD) experiments with a typical heating rate of 2.5 K/s. Samples could be cooled below 100 K via a liquid nitrogen dewar and heated up to 1300 K via resistive heating. ...
متن کاملCovalently bonded carbon nanotube – graphene hybrid material
We have witnessed tremendous growth in the area of nanomaterials for the past three decades. The discovery of fullerenes by Kroto et al. in 1985, was followed by the isolation of some more novel carbon nanomaterials, new allotropes of carbon. These include carbon nanotubes (CNTs) obtained by Iijima in 1991 and graphene isolated by simple exfoliation of graphite with a scotch paper by Novoselov ...
متن کاملInvestigation of Molecular Selenium Adsorption to the Outer Surface of Single Wall Carbon Nanotubes
In this study the adsorption of selenium molecule (Se2) on the outer surface of zigzag (5,0), (8,0) and (10,0) carbon nanotubes has been investigated. We examined number adsorbed orientations as well as different adsorption sites on nanotubes. The adsorption energies, equilibrium distances, energy differences between the highest occupied molecular orbital (HOMO) and lowest uno...
