The study and design of control, communication, and computing devices that rely on the movement of electrons in circuits containing semiconductors, thermionic valves, resistors, capacitors, and inductors. SeeElectronics (Chronology).
Electronics and Electrical Engineering
The study, design, and use of devices that depend on the conduction of electricity through a vacuum, gas, or semiconductor. Electrons and holes are the most important forms of charge carriers in electronic devices but ions also play a part.
