Schottky barrier ?

    Schottky barrier !! ?

    hi all

    something i cant understand in the schottky barrier diode
    i know that when electrons move from semiconductor(n type) to metal a depletion region appears in the n side so potentail difference is created
    so for electrons to move from S.c to metal they need to overcome this potential

    the question is:
    why the electrons to move from metal to sc ther have to overcome the barrier not the potential

    i really have a problem to understand the meaning of barrier
