5 Questions
What is a semiconductor?
A material with electrical conductivity between a conductor and an insulator, whose resistivity decreases as temperature rises and can be altered by introducing impurities.
How are the conducting properties of a semiconductor altered?
By introducing impurities (doping) into the crystal structure.
What is created when two differently doped regions exist in the same crystal?
A semiconductor junction.
What is the basis of diodes, transistors, and most modern electronics?
The behavior of charge carriers at semiconductor junctions.
Name three examples of semiconductors mentioned in the text.
Silicon, germanium, gallium arsenide.
