Low-voltage DC electroluminescent device using semiconductive band barriers with Cu2O

Abstract: To improve the efficiency of a DC Electroluminescent (DC-EL) device, we investigated the reduction of the driving voltage while maintaining the stability of the DC-EL device in this study. Mechanisms for both the current control and hot-electron generation under low voltage were embedded in the device. Usage of a p-Cu2O thick film with high-performance electrical properties for the formation of two semiconductive band barriers in series achieved these functions. The n-ZnO/p-Cu2O controlled current, and the p-C… Show more
