Correct option is D
· A P-N-P-N diode, commonly known as a
thyristor or
SCR (Silicon Controlled Rectifier), is a type of semiconductor device that is typically made of
silicon.
· Silicon is the most widely used material for semiconductor devices, including P-N-P-N diodes, due to its favorable properties such as stability, ease of manufacturing, and ability to operate at higher temperatures. It has a higher bandgap compared to germanium, which makes it more suitable for high-power and high-temperature applications.
