A comparative study of double gate MOSFET with asymmetric barrier heights at source/drain and the symmetric DG-SBFET

Double gate SBFET with asymmetric barrier heights at source/drain and the symmetric DG-SBFET are simulated. A comparative study between them is made. We have found that the DG-ASBFET is more appropriate for LOP and LSPT applications. Furthermore, the DG-ASBFET shows a better scale ability and better immunity to the short channel effects.
