Hi I was wondering how much quantum mechanics I should fit into my curriculum in order to to do research with nanoelectronics and optoelectronics in the future? At the moment I am an undergraduate working on both a BE and ME in Electrical Engineering at the same time (special scholars program) with that masters concentration in Photonics/Microelectronics. I do eventually plan on getting a PhD with research focused more in the nanoelectronics field. At the moment I can either only take an introductory quantum mechanics course or I can take that course along with the next level of quantum mechanics. The only problem with the later version is that I would need to take a prelim course in intro to mechanics which would be a completely extra class that wouldnt go towards either of my degrees. I was wondering if its worth going with the second choice even if it means the extra grad class (i take approx 20ish creds a semester and this would make it about 23). I will list the textbooks below that the two quantum classes use for a guideline to the material covered and the intro to mechanics course pretty much covers hamiltonians, lagrangians tensors etc. Intro to quantum course: Introductory quantum mechanics, Liboff Next level quantum course: Gottfried, Quantum Mechanics, Schiff, Quantum Mechanics I guess the more general question im getting at is just how involved are the electrical engineers researching in this field involved directly with the physics that have to do with these new nano-devices (quantum dots etc.) or is the role of the EE in this field researching ways for these new devices to actually be used so just understanding how they work will be enough?
