This course is a three-part series which explains the basis of the electrical, optical, and magnetic properties of materials including semiconductors, metals, organics, and insulators. We will show how devices are built to take advantage of these properties. This is illustrated with a wide range of devices, placing a strong emphasis on new and emerging technologies. The first part of the course covers electronic materials and devices, including diodes, bipolar junction transistors, MOSFETs, and semiconductor properties. The second part covers optical materials and devices, including photodetectors, solar cells (photovoltaics), displays, light emitting diodes, lasers, optical fibers, optical communications, and photonic devices. The final part of the series covers magnetic materials and devices, including magnetic data storage, motors, transformers, and spintronics. This course was organized as a three-part series on MITx by MIT’s Department of Materials Science and Engineering and is now archived on the Open Learning Library, which is free to use. You have the option to sign up and enroll in each modules if you want to track your progress, or you can view and use all the materials without enrolling.

The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.
