Linear current-voltage pattern, has been and continues to be the basis
for characterizing, evaluating performance, and designing integrated
circuits, but is shown not to hold its supremacy as channel lengths are
being scaled down. In a nanoscale circuit with reduced dimensionality in
one or more of the three Cartesian directions, quantum effects transform
the carrier statistics. In the high electric field, the collision free
ballistic transform is predicted, while in low electric field the
transport remains predominantly scattering-limited. In a
micro/nano-circuit, even a low logic voltage of 1 V is above the
critical voltage triggering nonohmic behavior that results in ballistic
current saturation. A quantum emission may lower this ballistic
velocity.
