In a semiconductor, current conduction is due______

Right Answer is:

Holes and free electrons

SOLUTION

In a semiconductor, current conduction is due to holes and free electrons.

Detailed Explanation

⇒ Current is the movement of charge carriers, such as free electrons, holes, and ions.

⇒ Electron current is the result of free electrons that are directed to move from one atom to another along a conductive path.

⇒ Because electrons have a negative charge, they are repelled by areas of negative polarity and are attracted to areas of positive polarity.

In semiconductors, as an electron jumps from one atom to another, it leaves behind a positively charged hole.

⇒ This positively charged hole attracts another negatively charged electron.

⇒ In essence, the two charge carriers switch positions with electrons moving in one direction (from negative to positive) and positively charged holes moving in the opposite direction (from positive to negative).

Both holes and electrons contribute to current conduction in semiconductors.

In p-type materials, holes outnumber free electrons, and they make up the majority of carriers. The majority of carriers in N-type are free electrons.

So, we conclude that, in a semiconductor, current conduction is due to both holes and electrons.
