Questions & Step-by-Step Solutions
In a forward-biased diode, the majority carriers are:
Step 1: Understand what a diode is. A diode is a semiconductor device that allows current to flow in one direction.
Step 2: Know the two types of semiconductor materials used in diodes: n-type and p-type.
Step 3: In n-type material, electrons are the majority carriers because they are more abundant.
Step 4: In p-type material, holes are the majority carriers because they are more abundant.
Step 5: When a diode is forward-biased, it means that the n-type side is connected to a positive voltage and the p-type side to a negative voltage.
Step 6: In this condition, electrons from the n-type region move towards the p-type region, and holes from the p-type region move towards the n-type region.
Step 7: Therefore, in a forward-biased diode, both electrons (from n-type) and holes (from p-type) are considered majority carriers.
