Hello folks,
I am familiar with both of terms that i speak of in title. But I cannot find a full answer, so I might as well ask the PhD'ers here. What is really happening in Zener and Avalanche breakdown? I have read Introduction to Zener Effect and Avalanche Effect and still feel confused.
And yes I get that impact ionization thing etc. But still, how does Zener differ from Avalanche breakdown? Why is doping so important? How come it doesn't damage the diode? Why is current constant? Why would it be constant when u exceeded the depletion zone(reverse bias), current should be proportional to voltage? (more voltage, more energy, more charges pulled out, more current) I am trying to get a full picture here. You may post something with detailed quantum mechanics, semiconductor theory.
I am very glad to learn. Thank you in advance.![[smile]](/data/assets/smilies/smile.gif "[smile] [smile]")
