This course is offered to introduce the junior students (III rd year) to the Materials Science and Engineering basics as well as the applications in optoelectronics and semiconductor devices.

The course is divided in four modules: First module introduces electronic structure of materials; Second module discusses electrical properties of metal, semiconductors and insulators; Third module discusses optical properties of materials; Fourth module introduces basic devices - p-n junctions, their application in solar cells and light emitting diodes, MOS devices, transistors.
