I'm not xt00, but based on age/out-of-printness I'm guessing it may be Datta's 1989 book "Quantum Phenomena (Modular Series on Solid State Devices, Vol 8)". His 1986 book "Surface Acoustic Wave Devices" is a distant second-best possibility, depending on what was in that one semiconductor device physics course.
Everything else seems to be in print still, though some are expensive (as typical of specialized books).
Was definitely part of the modular series, a small dark blue book.
It’s this one as the previous poster said.
"Quantum Phenomena (Modular Series on Solid State Devices, Vol 8)".
It’s referenced to by many other books from what I recall. So I decided to go hunting for it — and found that the explanations in Datta’s book were better than many of the books that came after it. I’ll see if I still have the book someplace.
