Q: In a p-n junction, which type of charge carriers are majority carriers in the p-type region? (2019)
Solution: In the p-type region of a p-n junction, holes are the majority charge carriers.
Steps: 4
Step 1: Understand what a p-n junction is. It is a semiconductor device made of two types of materials: p-type and n-type.
Step 2: Know that p-type material is created by adding certain impurities (dopants) to a semiconductor, which creates 'holes' (positive charge carriers).
Step 3: Recognize that in the p-type region, the majority of charge carriers are holes, which are the absence of electrons.
Step 4: Conclude that since holes are the most abundant charge carriers in the p-type region, they are referred to as the majority carriers.
