Hope I posted at the right part of the forum, anyway. I am a computer science student as such am required to take 2 courses in Physics. The first course was pretty much a walk in the park - college physics. But now for the second course it is crazy. I cant find a manual I can study from! The course is about a bit of quantum physics - really the basics, but then we have stuff like fermi energy and about how semiconductors are produced and how they work and stuff, and energy levels in a crystal and such stuff. The notes from class are pretty much a dissorganized, low quality explanations on this. Does anybody know any good manual for physics behind semiconductors and stuff that is used in the computers? Some of the question in last years sub-exams: What is the energy and wavelength of photons that are associated with line K alpha for Copper. Electrons in Copper have fermi energy of 7eV. Specific resistance of Copper is 17.5 Ohm-meters. What is the density of the conducting electrons. What is their average traveling speed in the copper wire of length 0.25 m that is wired on 12 V. and such...any ideas for a good manual or textbook for this? links to amazon or some resourceful webpages would be highly appriciated.
