Electronic band structure of a Carbon nanotube superlattice

By employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (CNT) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. Exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. The calculations are base...

Quantification of the quality of distribution is essential in carbon nanotube (CNT) composites since it reflects the homogeneity of the properties. In this work, an attempt is made to quantify the quality of dis...

Shrinking a carbon nanotube.

We report a method to controllably alter the diameter of an individual carbon nanotube. The combination of defect formation via electron irradiation and simultaneous resistive heating and electromigration in vacuum causes the nanotube to continuously transform into a high-quality nanotube of successively smaller diameter, as observed by transmission electron microscopy. The process can be halte...
