Question

42) In pure silicon elections and holes densities
are 105x1016/m3. If silicon is deped with
indium in a way that on doping hole densin
Then election
increases to 205x1022/m?
will be
density in doped semiconductor
(1) IX 109/m3 (2) 3x107m3 (3) 5X109/m3
(64) 7110%/m3 (5) 105 1109/m3.​

Answer 1

Answer 2

Answer:

Silicon is an element with four electrons in its outer shell. To make a p-type semiconductor extra materials like boron or aluminium are added to the silicon. These materials have only three electrons in their outer shell.
