Carbon nanotubes and other graphitic structures as contaminants on evaporated carbon films

چکیده

High-resolution electron microscopy (HREM) has been widely used in studies of fullerene-related carbons, and in particular has been applied extensively to the study of carbon nanotubes (Iijima, 1991; Ebbesen & Ajayan, 1992) and carbon nanoparticles (Harris et al., 1993; Saito et al., 1993). The purpose of this Note is to draw the attention of workers in this field to the fact that carbon nanotubes, nanoparticles and other graphitic carbon structures are sometimes present as contaminants on transmission electron microscope (TEM) support films. This could be a major cause of confusion in fullerene studies. Serious errors could arise, for example, in studies aimed at exploring new methods for nanotube synthesis.

Carbonaceous contaminants on support films for transmission electron microscopy

Evaporated carbon support films for transmission electron microscopy often contain carbonaceous contaminants. These include poorly graphitized carbon, fragments of graphite, and fullerene-like structures such as nanotubes and nanoparticles. In some cases, carbyne crystals may also be present. There are many examples in the carbon literature where these contaminants have been mistaken for sample...

Mesoscopic Interaction Potential for Carbon Nanotubes of Arbitrary Length and Orientation†

Mesoscopic tubular potential is developed for the description of the van der Waals interaction between straight single-walled carbon nanotubes (CNTs) of arbitrary length and orientation. The potential is formulated within a general continuum description of the van der Waals intertube interactions based on the integration of an interatomic potential over the surfaces of the interacting nanotubes...

Resonant Raman study on bulk and isolated graphitic nanoribbons.

Carbonaceous materials have been shown to graphitize up to different levels upon heat treatment, depending on the characteristics of their defects and the temperature reached during the heat treatment. In the literature there are reports on the annealing of materials, such as thin carbon films, graphite fibers, polyparaphenylene (PPP)-basedcarbons, cup-stacked carbon nanotubes, diamond-like car...

A density functional study on the mechanical properties of metal-free two-dimensional polymer graphitic Carbon-Nitride

Successful synthesis of the stable metal-free two-dimensional polymer graphitic carbon-nitride with remarkable properties has made it as one of the most promising nanostructures in many novel nanodevices, especially photocatalytic ones. Understanding the mechanical properties of nanostructures is of crucial importance. Thus, this study employs density functional theory (DFT) to obtain the mecha...

Towards solution processed all-carbon solar cells: a perspective

In this perspective, we describe a new type of photovoltaic all-carbon composites, in which single walled carbon nanotubes (SWCNTs) and fullerenes are directly co-assembled and processed in water using graphene oxide (GO) as a surfactant. Solar cells made with C 60 /SWCNTs/reduced GO as the active layer and an additional evaporated C 60 blocking layer yield a power conversion efficiency of 0.21...
