Which of the following is a semiconductor material

Electrical Engineering XYZ MCQs

Which of the following is a semiconductor material:

  1. Ge
  2. GaAs
  3. Si
  4. All of the above

Correct answer: 4. All of the above

Explanation: The correct answer is “All of the above.”

  1. Ge (Germanium): Germanium is a semiconductor material. It was one of the first materials used in the construction of semiconductor devices and played a significant role in the early development of transistors and other semiconductor devices.
  2. GaAs (Gallium Arsenide): Gallium arsenide is another semiconductor material commonly used in electronic devices, especially in high-frequency applications. It has properties that make it suitable for use in devices such as diodes, field-effect transistors (FETs), and integrated circuits.
  3. Si (Silicon): Silicon is perhaps the most widely used semiconductor material in modern electronics. It’s the backbone of the vast majority of semiconductor devices, including diodes, transistors, and integrated circuits. Silicon’s abundance, stability, and favorable semiconductor properties make it a cornerstone material in the electronics industry.

All three materials mentioned (Germanium, Gallium Arsenide, and Silicon) are semiconductors. They have properties that allow them to conduct electricity under certain conditions, but they can also act as insulators under other conditions, making them crucial for the functioning of various electronic devices.
