Principle of Semiconductor Devices Part I: Semiconductors, PN Junctions and Bipolar Junction Transistors
What are Semiconductors?
Semiconductors fall somewhere between a conductor and an insulator. Their resistance falls as temperatures rise, making semiconductor materials useful in products that require special conductive circumstances. Common semiconductor materials include germanium, gallium arsenide as well as altered forms of silicon dioxide. Semiconductors can pass currents more strongly in one direction, for example, or may be sensitive to light or heat. These materials are vital in electronic devices and electronic components. Without silicon crystal, for instance, we may not have integrated circuits. The properties of semiconductors are fascinating and provide us with the capability to create highly specialized circuits, devices, and a range of innovations. Our newest technology is possible because of the semiconducting power of things like pure silicon, so learning how they work could be a jumpstart to a lifelong career.
Learn about Semiconductors
Whether you're studying pure semiconductors or learning how to alter the conducting properties of other types of materials and crystal structures, this knowledge could uncover newer, more innovative forms of technology. Semiconductor technology is still evolving, and with the proliferation of our electronic devices, that research isn't going to stop any time soon. EdX.org offers courses and certifications that allow you to study the properties of semiconductors from the comfort of your own home or office. Courses are developed in partnership with leading institutions in the field and taught by teachers, researchers, and mentors with hands-on experience.
Semiconductor Courses and Certifications
Hong Kong University of Science and Technology offers a two-part series introducing you to the principles of semiconductors. You'll learn about the motion of semiconductors and the operational principles of some common semiconductors, including PN Junctions, photodiodes, solar cells, and Schottky diodes. Part two expands this knowledge into more complex semiconductors, including what makes a good conductor with MOS capacitors, and building MOSFETs. You'll learn about the electrical conductivity of MOSFETs, and use those electric currents to build things like digital camera sensors. Delft offers courses on Solar Energy and building semiconductor devices with photovoltaic properties that rely on solar power. You can also delve into Solid-state chemistry with MIT and understand how experts use the periodic table to predict the activities of certain materials such as their ability to conduct electricity.
Build a Career in Innovation with Semiconductors
Semiconductor chips, electronic circuits, and smaller and smaller microchips form the basis for our newest tech. You could build the next significant innovation by studying semiconductors. With your understanding of fundamentals such as the flow of electrons and the different types of semiconductors like p-type semiconductors and n-type semiconductors, you might make a considerable advance in the semiconductor industry. edX offers you the chance to understand what constitutes good conductors, sound insulators, and suitable semiconductors with courses and certifications. The path is open, and you could lead the way.
