What is the effect of temperature on the conductivity of semiconductors? (2019)

Step 1: Understand what conductivity means. Conductivity is how well a material can conduct electricity.
Step 2: Know what semiconductors are. Semiconductors are materials that can conduct electricity, but not as well as metals.
Step 3: Learn about charge carriers. Charge carriers are particles that carry electric charge, like electrons and holes in semiconductors.
Step 4: Recognize the role of temperature. Temperature is a measure of how hot or cold something is.
Step 5: Observe what happens when temperature increases. When the temperature of a semiconductor increases, more charge carriers are generated.
Step 6: Connect the dots. More charge carriers mean that the semiconductor can conduct electricity better.
Step 7: Conclude the effect. Therefore, as temperature increases, the conductivity of semiconductors increases.
