TOB

Top-of-the-Barrier (TOB) model

1. Extract density of states and electron velocity from the energy dispersion as the input data of the top-of-the-barrier model
2. Solve I-V and quantum capacitance from the self-consistent potential at the top of the barrier
3. Use the source side Fermi level to center Ioff

For example, use TOB model to evaluate the performance of III-V UTB (ultra-thin-body) nMOSFETs
