Describe the following term briefly:
Minority carrier injection in forward biasing.
Explain the following term:
Minority carrier injection in forward bias

उत्तर
Due to the applied voltage, electrons from the n-side cross the depletion region and reach the p-side (where they are minority carriers). Similarly, holes from the p-side cross this junction and reach the n-side (where they are minority carriers). This process under forward bias is known as minority carrier injection.
