What is the effect of doping on the conductivity of semiconductors?

Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity, but not as well as a conductor like copper.
Step 2: Know that pure semiconductors have a limited number of charge carriers (electrons and holes) that can move and carry electricity.
Step 3: Learn about doping. Doping is the process of adding small amounts of certain materials (dopants) to a semiconductor.
Step 4: Recognize that dopants can be either 'n-type' or 'p-type'. N-type dopants add extra electrons, while p-type dopants create more holes (places for electrons to go).
Step 5: Realize that by adding these dopants, we increase the number of charge carriers in the semiconductor.
Step 6: Conclude that more charge carriers mean better conductivity, so doping increases the ability of the semiconductor to conduct electricity.
