Yes, electrons can propagate around the circumference of the nanotube. They're called 1-dimensional because most of their practical applications employ their conductive properties along the long axis of the wire. But the structure of the tube about its circumference (specifically its twist, or helicity) strongly affects its overall electronic structure: namely, whether the tube is metallic or semiconducting.gildomar said:Can carbon nanotubes support electron propagation perpendicular to the axis? That is, can there be circular current flow on the tube's perimeter, not just the linear flow parallel to the axis? Because I reading that it's generally considered a 1-dimensional conductor.

Circular electron propagation in carbon nanotubes is a phenomenon where electrons move in a circular motion along the length of the nanotube. This behavior is due to the unique structure and properties of carbon nanotubes, which allow for the formation of a strong electric field that causes the electrons to move in a circular path.
Circular electron propagation in carbon nanotubes occurs due to the presence of a strong electric field along the length of the nanotube. This field is generated by the unique arrangement of carbon atoms in the nanotube structure, which creates a gradient in the electron density. This gradient causes the electrons to move in a circular motion, similar to how a charged particle moves in a magnetic field.
Circular electron propagation in carbon nanotubes has potential applications in various fields, including electronics, energy conversion, and quantum computing. It can be used to create high-speed electronic devices, efficient energy storage and conversion systems, and for manipulating and controlling individual electrons for quantum computing.
Circular electron propagation in carbon nanotubes is studied using various experimental techniques, such as scanning tunneling microscopy, Raman spectroscopy, and electron transport measurements. These techniques allow researchers to observe the behavior of electrons in the nanotubes and understand the underlying mechanisms of circular electron propagation.
One of the main challenges associated with circular electron propagation in carbon nanotubes is controlling and manipulating the electrons in a precise manner. This requires advanced nanofabrication techniques and precise control over the electric and magnetic fields in the nanotubes. Additionally, there are challenges in integrating carbon nanotubes into practical devices and scaling up production for industrial applications.
