electric field in undoped or lightly doped Double-Gate MOSFETs (DG-MOSFETs) and
Schottky barrier Double-Gate MOSFETs (SB-DG-MOSFETs) in subthreshold region is
presented. Solutions for constant and linear boundary conditions are used to model step by
step the potential and the electric field for these structures of Double-Gate MOSFETs.
