Question:

Leakage Current in the Silicon Semiconductor is in the order of_________

1. Amps
2. Nano Amps
3. milli Amps
4. micro Amps

Answer:

The correct option is (2)
Leakage Current in the Silicon Semiconductor is in the order of Nano Amp due to its wider band gap.

Here’s a detailed explanation of why this property results in lower leakage currents:

Explanation:

Band Gap and Leakage Current: Silicon has a relatively wide band gap of about 1.12 eV. This means that fewer electrons have enough thermal energy at room temperature to jump from the valence band to the conduction band compared to materials with smaller band gaps. The wider band gap makes fewer charge carriers available for conduction under non-ideal conditions (like reverse bias conditions in diodes or off-state transistors), thereby reducing the leakage current.
