Which risk increases when the electron's energy approaches the Schottky barrier height?

💡 Explanation

Increased thermionic emission occurs because at Schottky barriers, electrons can overcome this barrier with sufficient thermal energy; therefore, the emission current rises exponentially rather than remaining constant as influenced by tunneling effects.
