본문내용
Zener breakdown is what happens by tunneling. If you don't know Tunneling, go to Google and find it. What are the basic prerequisites for tunneling? It is just the thickness. In the figure above, the distance W must be very narrow for electron tunneling from the fence band (V.B) of the P type to the conductive band (C.B). The reason why the electron tunnels is because of the powerful electron field because of the reverse bias.
