摘要：A novel ZnO homojunction light emitting diode (LED) with n-ZnO-nanorods/p-ZnO:As-film structure is fabricated on the GaAs substrate. Desirable rectifying behavior and distinct ultraviolet electroluminescence emission are observed from this novel structured ZnO homojunction LED. The well-aligned n-type one-dimensional ZnO nanorods are synthesized by a simple wet chemical bath deposition. To fabricate the ZnO nanorods on the GaAs substrate, a key two-dimensional intermediate ZnO:As film layer is employed. The ZnO:As film is grown by metal organic chemical vapor deposition followed by an annealing treatment. Moreover, the intermediate ZnO:As film is also used as the p-type layer of the ZnO LED.
