Question

When p-type and n-type regions are formed in a single crystal, which carriers initially diffuse from each side?

विकल्प

• Holes from the p-side and fixed ions from the n-side

• Holes from the p-side and electrons from the n-side

• Electrons from the p-side and holes from the n-side

• Fixed ions from the p-side and electrons from the n-side

Answer 1

The concentration difference causes holes to diffuse from the p-side and electrons from the n-side. Their movement across the junction begins the formation of the depletion region.
