Exam Question

Semiconductor devices:
Semiconductor devices are electronic components utilizing the properties of semiconductor materials. These materials are neither good conductors nor good insulators; examples include silicon and germanium. Their conductivity can be significantly altered by adding trace amounts of other elements, a process called doping. Diodes, transistors, photocells, and thyristors are common examples used in electronic circuits.
Advantages of Semiconductor Devices Over Thermionic Devices:
Smaller size
