After reading about Waves, electricity and Magnetism, Thermal physics etc. you might still wonder…just how do the electronic devices work? Yes, this course covers the physics behind crystals and the range of electronic behaviour all the way from the most metallic to highly insulating materials. And that thing in between…semiconductors. And how heat or electrical conduction happens in such solids. We also discuss the physics behind some of the latest technological developments of this century. With a little help from quantum mechanics, this advanced theoretical course explains all of this. And then some.
