I think Option B is the correct answer.

Sankar said:   7 years ago
B is the answer.

Saurabh said:   6 years ago
No it is Indirect gap semiconductor.

Ishu said:   6 years ago
This is to increase the recombination rate.

Sri said:   5 years ago
Gold is a recommendation agent it is used to increase the recommendation rate.

So, the correct answer is A.

Option B.

It reduces the recombination rate.

Ashish mahar said:   4 years ago
Yes, It's option B. I too agree.

Bindu Raj said:   2 years ago
Yes, Option B is the correct answer.

Gold is often diffused into silicon p-n junction devices to modify the electrical properties of the semiconductor material.

It does not have a direct relation to the recombination rate or make silicon a direct gap semiconductor.
