This article is superb! I sure wish it been around a few years ago when I was taking my semiconductor physics course; now that I've read these first 3 articles, I finally understand the difference between electrons and holes, and understand what makes pn junctions work.

Well done, Dan, on making a notoriously tough subject understandable!

It is a great article.. thanks! I especially appreciate the inclusion of an explanation on conventional vs REAL current flow theory, it would be nice if the conventional theory would finally die out of our educational institutes, but it is a slow process.

Thank you very much for writing this article. I could never understand how that all worked until I read this series on semiconductor physics. It has been a great eye opener to me. Thanks a lot.

Hi!

Congratulations, very good article!
It really helped to understand semiconductors better.
I'm looking forward to the next part
--> Then maybe at last I will understand what happens in these CPU's

ciao, roberto

Wonderful work in explaining semiconductor behavior, very clear and concise. I wish I had this when I was first taught the properties of semiconductors 33 years ago. Keep up the good work!

Dan, this is a thoughtful presentation. A good contribution to Hardwareanalysis. I look ahead to part 4.
Thanks
