Which of the following is metal compound semiconductor?
- Copper
- Silver
- Aluminium
- Germanium
The Correct Option is D
Solution and Explanation
Germanium (Ge) is a metalloid that can behave as a semiconductor when used in electronic devices. It has properties that allow it to conduct electricity under certain conditions, making it suitable for use in semiconductor applications. Copper (A), silver (B), and aluminium (C) are not typically used as semiconductors.
So, the correct answer is option (D): Germanium.
