Ballistic conduction

Ballistic conduction refers to the type of electrical conduction that occurs when electrons move through a material with minimal scattering, resulting in a high level of conductivity. In ballistic conduction, the electrons move in a straight line, like a ball, hence the name “ballistic”. This type of conduction is typically found in very pure materials with low levels of impurities, such as single-walled carbon nanotubes, graphene, and some high-quality metal wires.

In ballistic conduction, the electrons are not subject to the usual resistive forces that arise from the collision of electrons with lattice atoms or impurities in the material. As a result, the electrical resistance of the material is very low and the electrons can travel over long distances without losing much energy. This makes ballistic conduction an important phenomenon for the development of new, high-performance electronic devices, such as transistors, diodes, and interconnects.

In addition to its potential applications in electronics, ballistic conduction also plays an important role in our understanding of the fundamental properties of materials. For example, the study of ballistic conduction has led to new insights into the nature of electron-electron and electron-phonon interactions in materials, and has helped to clarify our understanding of the quantum mechanical behavior of electrons in solids.
