The most commonly used semiconductor is
Correct answer: B. silicon
- A. germanium
- B. silicon
- C. gallium
- D. aluminium
Explanation
Silicon is the most commonly used semiconductor material in the electronics industry. It is widely used for manufacturing transistors, diodes, and integrated circuits due to its excellent semiconductor properties.Incorrect Options and Explanations: (a) germanium - Germanium was used earlier, but silicon has become more prevalent in modern electronics. (c) gallium - Gallium is not as commonly used as silicon in general electronic applications. (d) aluminum - Aluminium is a metal and not a semiconductor material.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
