Question

An intrinsic semiconductor can be converted into an extrinsic semiconductor
by addition of .................. This process in called ..................

Answer 1

Answer:

In order to convert into n-type semiconductor, the concentration of electrons must be greater than number of holes, electrons are introduced by doping the intrinsic semiconductor with elements like Phosphorous Antimony Arsenic which have 5 electrons in their last orbit and can give one electron thereby increasing theAn intrinsic semiconductor is an undoped semiconductor. This means that holes in the valence band are vacancies created by electrons that have been thermally excited to the conduction band, as opposed to doped semiconductors where holes or electrons are supplied by a “foreign” atom acting as an impurity.

Answer 2

$Answer$

➡️An intrensic semiconductor can be converted into an extrinsic semiconductor by addition of pentavalent atom . This process is called N - type semiconductor.
