n-type and p-type semiconductors!
added in Semiconductors

Why are impurities added to pure semiconductors?
Adding impurities, a process called doping,
enhances their conductivity, making them essential for creating devices like diodes and transistors.
There are two types of doping
1.n-type semiconductor: Formed by adding materials like phosphorus, which have extra electrons.
2.p-type Semiconductor: Created by adding
elements like boron, which have three electrons in their valence shell, creating 'holes.
