A Review of Carbon Nanotubes Electrical Properties for Future Nanotechnology Applications

Abstract

Interest in the field of carbon nanotubes is due to unique physical properties and to significant prospects for applied applications. In this review, the quantum nanostructures with outstanding electrical properties are studied on electron emission performance optimization of carbon nanotubes with the factors affecting aligning as mechanical elasticity in bending related to electronic structure. The phenomenon of field emission producing current when an electric field is applied to a conductor is also discussed. The carbon nanotubes applications in nanotechnology are clarified in this work and it can be metallic or semiconductor depending on diameter and chirality with high emission and conductivity properties to create electronic devices.
