N-Type Silicon Semiconductor
Visualizing majority and minority carriers in doped silicon
Simulation Parameters
Theoretical Background
This simulation demonstrates the behavior of charge carriers in n-type silicon, where pentavalent atoms (like Phosphorus) are added as dopants to pure silicon.
N-Type Semiconductor Characteristics
In n-type silicon:
- Electrons are majority carriers (from donor impurities)
- Holes are minority carriers (from thermal generation)
- Pentavalent atoms (5 valence electrons) serve as dopants
The correct answer to the question is: Electrons are majority carriers whereas holes are minority carriers in an n-type silicon atom.
Adjust the dopant concentration to see how it affects the number of free electrons, and the temperature to observe thermal generation of electron-hole pairs.
