Slide 2 - What is a Semiconductor?

Electrical conductivity between conductors and insulators
Conductivity modified by doping (impurities)
Examples: Silicon (most common), Germanium, Gallium Arsenide (lasers, solar cells)
Basis for diodes, transistors, and modern electronics

Slide 3 - Doping: n-Type vs p-Type

n-Type

Group V dopants (P, As, Sb)
Donors release free electrons
Majority carriers: electrons (-)

p-Type

Group III dopants (B, Ga, In)
Acceptors create holes
Majority carriers: holes (+)
Forms p-n junctions
