Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary semiconductor element?Silicon (Si), a Group IV element from the periodic table
2. What is the key semiconductor junction?The p-n junction, fundamental to diodes and transistors
3. Why do semiconductors become more conductive when they get hot?When a semiconductor heats up, the extra energy moves more electrons into the conduction band or creates more holes in the valence band, letting electricity flow more easily.
4. How does doping change a semiconductor?Doping adds tiny amounts of other atoms to the crystal. This creates extra electrons (n‑type) or holes (p‑type) that control how the material conducts.

Band Gap: The energy range in a solid where no electron states can exist, crucial for semiconductor properties.
Charge Carrier: Mobile particles (electrons or holes) responsible for electrical current in a material.
Valence Band: The highest energy band containing electrons in a solid at absolute zero temperature.
Conduction Band: The lowest energy band that is empty or partially filled with electrons, allowing for electrical conduction.
