Prof. Lundstrom is a giant in semiconductors and it’s exciting to see him publish this book.
akshatjiwan•1mo ago
A few years ago I took his course on thermoelectricity and really liked his way of teaching. The videos were short and to the point and yet gave me all that I needed to know about the topic.

Here's the link in case anyone s interested

It turns out that this is a part of an entire series of textbooks focused on semiconductors. https://www.worldscientific.com/series/neelns

As the editors note, this series is meant to be an intellectual successor to the Semiconductor Electronics Education Committee (SEEC) books that were published in the 1960s.

As someone unfamiliar with this field, I'm amazed at how readable this is. Must be a great professor.
kridsdale3•1mo ago
The best class I took in EE school was the 400 level course on this material.

Mathematically had us working from Schrödinger to LEDs and Transistors over the course of 4 months. Changed my whole perspective on shit.

> Mathematically had us working from Schrödinger to LEDs and Transistors over the course of 4 months.

What were the books used for this?

kridsdale3•1mo ago
The professor's in-progress manuscript. Sorry, but I didn't retain any information from then in order to look it up, that was 20 years ago.
barrenko•1mo ago
This would be both math and physics and chemistry?
osigurdson•1mo ago
Often you would study this type of material in Electrical or Computer Engineering.
IAmBroom•1mo ago
And Physics, but probably not Chemistry.
fc417fc802•1mo ago
It's touched on in chemistry, generally under the field of materials science. After all that's the bastard child of physics and chemistry that semiconductors fall under.

I say "generally" because obviously physical chemistry and inorganic chemistry also overlap with it a bit at the edges.

A slightly different audience, probably, but I was greatly assisted by Intuitive IC Electronics by Thomas Fredriksen.
