Anyone with semiconductor bandstructure calculation experience ?...

[amal banerjee]

All you electronics gurus here, anyone with band structure calculation
experience ? I have written a set of C and Python programs to do these
types of calculations, and would like to ask a few questions about the
results I am getting.

Babylonians have all this well documented on tablets preserved since 3500 BC. See the archives.

Electronic designers seldom get involved with device physics. We buy
parts and connect them to one another. That\'s a few steps up the
abstraction stack from the physics.

I seem to run into people here in the Phoenix, AZ area once in a while
that had jobs in the semiconductor industry and seem to know about
these things. Old physics majors, etc. Sorry I don\'t have a list or
know how to get a hold of them, really. Not sure they even program
though ?

Amazing. Is there any way to award these ancient Babylonian physicists|scientists with a physics
Nobel to recognize their knowledge about structure of matter, even before Newton formally
started the field of physics ?

Their solid state expertise centered on clay tablets, which they were
super great at.

WOW. Those calculations are equivalent to hybridizing orbitals to model
all the bonding in 3D solid materials, and get rather complex (as well as tricky,
since a small amount of impurities makes experimental results mismatch
what the theory says). It\'s usually a supercomputer application, though
one example, the Kronig-Penney model, can be useful as a lecture-hall
introduction to the process.

Aside from using the K-P as a test case, any deep knowledge is going to
take a good library search.
