Abstract

By employing lithium and nitrogen codoping method, p-type zinc oxide (ZnO) films have been prepared, and the p-type conduction can maintain for 207 days. ZnO p–n junctions have been constructed based on the p-type ZnO. Under the drive of continuous current, obvious emission has been observed from the p–n junctions, and the ZnO p–n junction light-emitting devices (LEDs) can still work after placing in air ambient for 180 days.
