Abstract

ZnO films are grown by the ultrasonic spray pyrolysis method on ZnO seeding layer deposited on Si (100) by pulsed laser deposition. The resultant film possesses a columnar microstructure perpendicular to the substrate and exhibits smooth, dense, and uniform morphology. The preferred orientation along the c-axis of the film is significantly enhanced compared to that without the seeding layer. ZnO film grown on ZnO-seeded silicon exhibits higher hall mobility, lower resisitivity, and higher photoluminescence intensity.
