Course Description

This course will explain the basis of the electrical, optical, and magnetic properties of materials including semiconductors, metals, organics and insulators, and will show how devices are built to take advantage of those properties. It is illustrated with a wide range of devices, placing a strong emphasis on new and emerging technologies. Applications presented include diodes, transistors, photodetectors, solar cells (photovoltaics), displays, light emitting diodes, lasers, optical fibers and optical communications, photonic devices, magnetic data storage, motors, transformers and spintronics.

I felt it was a bit sophisticated than it acutally claims. Crytallograpy Basics are a must in order to understand some of the most profound contents in this course. Prof.Ross's teaching was really good but as i said it was put up in edx as an introductory course but in MIT their are two courses taken by undergraduates prior to this one in order to fully appreciate the depth of it you can check it here in the OCW Site , it would've been a bit comprhensive if 2-3 weeks were alloted to explain those requisites

This wide-ranging course covers three largely independent technology subject areas and, importantly, key devices that have emerged from them. Prof. Ross begins each topic -- semiconductors, photonics and magnetics -- with a thorough foundational introduction, and then moves on to applications and devices. The semiconductor unit, by far the most rigorous, includes an introduction to diodes, transistors, and photovoltaics. Photonics takes you through lasers, LEDs, liquid-crystal displays, and optical fibers. Magnetics begins with a review of what you learned in freshman physics and chemistry but proceeds to the design of storage devices, some familiar (like disk drives) and some more exotic ("spintronic" media). Prof. Ross's lectures are excellent -- clear, articulate and easy to follow. They represent an online version of the residential 3.15 course and were prepared for MIT students.

Prof. Ross begins each topic -- semiconductors, photonics and magnetics -- with a thorough foundational introduction, and then moves on to applications and devices. The semiconductor unit, by far the most rigorous, includes an introduction to diodes, transistors, and photovoltaics. Photonics takes you through lasers, LEDs, liquid-crystal displays, and optical fibers. Magnetics begins with a review of what you learned in freshman physics and chemistry but proceeds to the design of storage devices, some familiar (like disk drives) and some more exotic ("spintronic" media). Prof. Ross's lectures are excellent -- clear, articulate and easy to follow. They represent an online version of the residential 3.15 course and were prepared for MIT students. Prof. Ross has generously made them available through edX, but she did not participate in the edX course itself. Instead, a course manager did an excellent job administering homework assignments and exams, answering our questions, and keeping everything on track. The biggest surprise, for many, was the difficulty of some of the homework assignments and exam questions given the easily followed lectures. While you could always thread back from the answers to a topic covered in lecture, following that thread when actually trying to solve the problem was often quite challenging, even occasionally mystifying. For the semiconductor unit in particular, a textbook is essential. Fortunately, Prof. Chenming Hu has written perhaps the best one out there and offers it free online. In sum, this is a well-presented, well-organized introduction to key topics in materials technology that emphasizes device applications without short-changing the fundamentals.
