Introduction to Semiconductors, PN Junctions and Bipolar Junction Transistors (edX)

An intuitive approach to operational principles of semiconductor devices. The course covers PN junction diodes, optical sensors, solar cells, LEDs, and Bipolar Junction Transistors. As a topic of study, semiconductor devices offer a unique challenge due to the complex mathematics involved. In this course, we take a more intuitive approach to explore the underlying concepts. Eschewing mathematics, we use engaging animations to help you visualize the working principles of many common semiconductor devices.

Whether you are completely new to the subject or an experienced engineer, this course will give you a different perspective and a new way to look at the behaviors of semiconductor devices.

Reducing the reliance of equations does not mean the depth of the material is sacrificed. In fact, the course provides even more in-depth explanations of key concepts. We shift the focus from quantitatively evaluating the behavior of semiconductor devices to intuitively visualizing the semiconductor device actions.
In addition, the course offers a wide array of content - from basic PN junctions to modern nano-electronic circuit and systems. Besides covering the existing technologies, the course also explores the development of the industry into the future.
This course is part of the Principle of Semiconductor Devices Professional Certificate.

The primary goal of the course is to enable the student to understand what semiconductors are, and why they are important to the electronics industry. Students will first learn and understand why some materials are insulators and others are conductors, and will learn how these properties can be modified. The course also explores other situations where the conductivity of an insulator can be drastically changed, such as the situation inside a bolt of lightning or inside a semiconductor.
