Think about the dopants used.
What type of atom is used for p-type doping?
Consider the valence electrons.
What are the majority carriers in an n-type semiconductor?
Consider the type of charge carriers that increase with doping.
True or False: In a p-type semiconductor, electrons are the majority carriers.
Reflect on the nature of doping in p-type materials.
Explain how the doping process affects the energy band structure of a semiconductor.
Consider how the addition of dopants modifies band formation.
