In a p-n junction, potential barrier of 200‌meV exists across the junction. A hole with a kinetic energy of 300‌meV approaches the junction. Let E1 and E2 be kinetic energies of the hole when it crosses the junction, while it approaches the junction from the p-side and n - side respectively: The value of ‌
