Question

Commonly used semiconductors are ....................... and ......................... Fill in the blanks by choosing correct words from the list given : (tin and lead, heat and light, magnetic field, magnet,silicon and germanium, chemical)

Answer 1

The ans is Silicon and Germanium.

Answer 2

Out of the following, tin and lead, heat and light, magnetic field, magnet, silicon and germanium, chemical, commonly used semiconductors are silicon and germanium.

Both these elements have four valence electrons in the outer shell which makes the formation of crystal lattices easy.

Due to this, the same dopants can be used for both the elements.
