Characterization of white light emitting diodes based ZnO nano structures grown on p-Si

Klason, Peter et al. (2007)

In this paper ZnO nanorods and nanodots (with and without a SiO2 buffer layer) were grown on p-Si, forming p-n heterojunctions. The nanorods devices showed no electroluminescence (EL) emission but a rectifying behavior with a breakdown voltage around -4V. The nanodot devices showed EL emission under ...
