What process are the majority carriers produced?

Majority carriers in a semiconductor are produced through the doping process, where specific impurities are intentionally added to the pure semiconductor material. For n-type semiconductors, elements with extra electrons (like phosphorus) are added, resulting in excess electrons as majority carriers. For p-type semiconductors, elements with fewer electrons (like boron) create "holes," resulting in holes as majority carriers. This controlled introduction of dopants alters the electrical properties of the semiconductor, facilitating its use in electronic devices.
