Classify each of the following as being either a p-type or an n-type s

1.	Classify each of the following as being either a p-type or an n-type semi-conductor. Give reason-(a) Si dopped with In (b) Si dopped with P
Answer» (a) p-type, because In has 3 valence electrons. Holes are produced which can move through the crystal like positive charge. (b) n-type, because P has 5 valence electrons. The fifth electron becomes delocalised and is free contribute to electrical conduction.
