The main difference between nanoscale electronic devices and traditional electronics lies in their size and the resultant properties. At the nanoscale, materials exhibit different physical, electrical, and chemical properties due to quantum confinement, surface-to-volume ratio, and other [quantum mechanical](https://en.wikipedia.org/wiki/Quantum_mechanics) effects. For instance, [carbon nanotubes]() and [graphene]() have exceptional electrical conductivity and mechanical strength, which traditional materials cannot match.
