    An approximate two-order increase in magnitude in electroluminescence was observed for the metal-oxide-silicon tunneling diodes with oxide grown at 900 °C, as compared to 1000 °C. The x-ray reflectivity revealed that the oxide grown at 900 °C has rougher interface than that grown at 1000 °C. The role of interface roughness can be understood in a model composed of phonons and interface roughness. An external quantum efficiency of approximately 10-6 was obtained using Al electrodes.
