Abstract :
We present a self-consistent 2-D quantum-mechanical model for charge distribution in cylindrical gate-all-around devices with computation of the gate tunneling current. The validity of 1-D approximations for the charge and the gate current is discussed, assessing the validity of a previously proposed analytical approximation for the tunneling current in the Fowler-Nordheim regime.
