Resumen

Analytical, physically-based, models for the threshold voltage and the subthreshold swing of undoped cylindrical gate all around (GAA) MOSFETs have been derived at low drain-source voltage based on an analytical solution of the two-dimensional (2-D) Poisson equation (in cylindrical coordinates) with the mobile charge term included. The new model has been verified by comparison with 3-D numerical simulations of devices with different channel lengths and thickness; the observed agreement with the numerical simulations is quite good. © 2006 Elsevier Ltd.
