Electrical Properties of Materials

Abstract

These lectures will not make you an expert in quantum mechanics nor will they enable you to design a computer the size of a matchbox. They will give you no more than a general idea. If you elect to specialize in solid state devices you will, no doubt, delve more deeply into the intricacies of the theory and into the details of the technology. If you should work in a related subject then, presumably, you will keep alive your interest, and you may occasionally find it useful to be able to think in quantum-mechanical terms. If your branch of engineering has nothing to do with quantum mechanics, would you be able to claim in ten years’ time that you profited from this course. I hope the answer to this question is yes. I believe that once you have been exposed (however superficially) to quantum-mechanical reasoning, it will leave permanent marks on you. It will influence your ideas on the nature of physical laws, on the ultimate accuracy of measurements, and, in general, will sharpen your critical faculties.
