Which outcome affects Schottky barrier diode behavior when ambient temperature significantly decreases?

💡 Explanation

When the ambient temperature decreases, the thermal energy available for electron tunneling decreases because the Fermi-Dirac distribution narrows near the Fermi level, reducing the tunneling probability through the Schottky barrier. Therefore, the tunneling current is reduced, rather than increased reverse current, decreased barrier potential, or eliminated rectification, which require other driving conditions like defects or increased voltage.
