    Hey Guys,

    I've been posting a lot on the forum recently, and I really appreciate everyone's help.

    I have a quick question about Schottky diodes. From what I've read, when a Schottky diode goes from forward bias to reverse bias there is no reverse current and no recovery time because there are no holes in the metal and thus no charge storage. What doesn't make sense to me is that despite the lack of holes, isn't there an excess of electrons from the n-type material within the metal? Wouldn't these electrons return to the n-type material after the diode is reverse biased?
