10 Questions
What is an intrinsic semiconductor also known as?
Undoped semiconductor
How are the number of charge carriers determined in an intrinsic semiconductor?
By the properties of the material itself
What is the relationship between the number of excited electrons and the number of holes in an intrinsic semiconductor?
n = p
When can a doped semiconductor still be intrinsic?
When doped with both donors and acceptors equally
What can affect the electrical conductivity of chemically pure semiconductors?
Crystallographic defects of technological origin
What is the function of a p–n junction in a semiconductor device?
Allow electric current to pass through the junction only in one direction
How are p-type and n-type regions created in a semiconductor?
By doping the semiconductor with different types of dopants
What are p-type and n-type semiconductors named after?
The excess of holes and excess of electrons, respectively
What electronic devices are p–n junctions fundamental to?
Diodes, transistors, solar cells, LEDs, and integrated circuits
How is the junction of a p–n junction different from a metal–semiconductor junction?
The p–n junction allows current flow in one direction, while the metal–semiconductor junction allows current flow in both directions
