Course Description

This course describes and discusses physical foundations of today's diodes, transistors, light-emitting diodes and semiconductor lasers which are present in computers and electronic or optoelectronic gadgets and equipment. Special attention is given to fundamental concepts of quantum mechanics: wave-particle duality, uncertainty principle, and manifestations of quantum phenomena in macroscopic world with focus on electronic devices. The course will be particularly useful to engineers who plan designing electronic circuits or working in optics.
