Defect-related white-light emission from ZnO in an n-Mg 0. 2Zn 0. 8O/n-ZnO/SiO x heterostructure on n-Si
JOURNAL OF ELECTRONIC MATERIALS, pp. 652-655, 2010.
An n-Mg0.2Zn0.8O/n-ZnO/SiO (x) (x < 2) heterostructure has been fabricated on n-Si by sputtering and electron-beam evaporation. The device showed nonrectifying behavior, and emitted strong white light under reverse bias with positive voltages applied to n-Si. The white-light electroluminescence (EL) is believed to result from electron-hol...More
