“…We have found that a large fraction of the cones are stable against Jahn-Teller distortion of bond lengths [8]. This is contrary to what is the case for the fullerenes, where very few stable topologies have been identified outside the so-called leapfrog series [9].…”

“…The well-defined shape of these cones, their non-centrosymmetric nature, as well as recent predictions of subtle electronic properties that are distinctly different from other types of carbon-including the possibility of existing as permanent dipoles or stable conic anions and cations [24,29]-suggest that these carbon nanoparticles can be important for understanding the structure-property relationships of carbon polymorphs in general. Applications taking advantage of this particular topology and morphology, e.g.…”

Large-scale production of conical carbon nanostructures is possible through pyrolysis of hydrocarbons in a plasma torch process. The resulting carbon cones occur in five distinctly different forms, and disc-shaped particles are produced as well. The structure and properties of these carbon cones and discs have been relatively little explored until now. Here we characterize the structure of these particles using transmission electron microscopy, synchrotron x-ray and electron diffraction. The carbon nanocones are found to exhibit several interesting structural features; instead of having a uniform cross-section, the walls consist of a relatively thin inner graphite-like layer with a non-crystalline envelope, where the amount of the latter can be modified significantly by annealing. The cones appear with a well-defined faceting along the cone edge, demonstrating strict long-range atomic ordering; they also present occasional examples of symmetry breaking, such as two apexes appearing in the same carbon nanocone.

“…The open-ended carbon cone can be established by cutting 1-5 sectors of angle 608 from a graphene sheet and joining the edges made by the cut, with 1-5 pentagons at the apex [15,16]. These carbon structures have recently been investigated by transmission electron microscopy [17,18].…”
