EECS 381: Electronic Properties of Materials

Quarter Offered

Fall : 1-1:50 MWF ; Mohseni

Prerequisites

EECS 223 or consent of Instructor.

Description

COURSE GOALS: The course is designed to provide the opportunity for students from different backgrounds to undertake study and research in solid state engineering and electronic materials. For those students who look toward an industrial position after graduation, this course is designed to widen background in material engineering and help them to meet the industry demand. For students who plan on graduate studies, it provides an excellent opportunity to prepare themselves for advanced study in a variety of different areas of solid state engineering and material science: metals, semiconductors, superconductors, optical, magnetic and amorphous materials. The course is meant to create the background needed to understand the physics of device operations and also prepare students for advanced courses in solid state and quantum electronics.
