Question
Which of the following is a semiconductor?
Answer Options
- A) Copper
- B) Silicon
- C) Carbon
- D) Silver
Correct Answer: B
Explanation
A semiconductor is a material that has electrical conductivity properties between that of a conductor (like copper) and an insulator (like glass). This unique property allows these materials to be used to build controllable electronic switches like diodes and transistors.
The most common and important semiconductor material used in electronics today is Silicon. It is the raw element used to construct virtually all modern electronic components, including integrated circuits (T6D09).
