9. What Is A Iii-v Semiconductor?
A semiconductor made from elements in columns III and V of the periodic table.
10. What Mathematical Formula Most Accurately Predicts The Fermi Level Of A Semiconductor?
Fermi-Dirac distribution.
11. What Are The Four Terminals Of An Fet Transistor?
- Source
- gate
- drain
- body

Valence and conduction
17. What Is The Reason For Reducing Drain Doping In A Metal-oxide Semiconductor Device Design?
To improve breakdown voltage.
18. What Is A Semiconductor?
The combination of a conductive material, and an insulator.
19. What Does ‘doping’ Do?
Changes a semiconductor’s behavior.
20. When Silicon Has Been Doped, What Does This Mean?
Impurities have been added that alter its electronic properties in a controllable way.
21. What Is Doping?
The process of deliberately adding impurities to affect conductivity is called Doping.
22. Why Are Semiconductors Important?
They successfully replaced vacuum tubes as the primary way to compute data.
