Abstract

Electrically pumped random lasers are realized in ZnO nanocrystallite films in a simple metal-oxide-semiconductor structure. By introducing an i-ZnO layer, a threshold current of 6.5 mA is obtained. The reported results provide a simple route to electrically pumped random lasing (see figure) with relatively low threshold, a significant step towards the future applications of this kind of laser.
