determining the barrier height. But, drain gets also some control as it is electrostatically
coupled to the gate. E E e t a G e d c u n d n I i a r D

(exponentially) increased. But as the Fermi level at drain is at lower potential than that of the
source, the increase in the number of electrons traversing from source-to-drain is more than
that of for drain-to-source. Accordingly,
