In case of semiconductors, recombination is

Question 1

In case of semiconductors, recombination is
1. Merging of two electrons
2. Merging of two holes
3. Merging of one electron and one hole
4. Merging of outside electron with another semiconductor electron

Question 2

Correct Answer - Option 3 : Merging of one electron and one hole

The merging of one electron and one hole in semiconductors is known as recombination.

Recombination:

Semiconductors are characterized by two types of mobile carriers, electrons in the conduction band and holes in the valence band; Both bands are separated by an energy gap
When an electron loses energy and falls into the valance band, it gets neutralized by a hole which absorbs its energy; This process is called recombination and the energy of recombination will emerge as a photon
