摘要：

We study the surface morphology evolution of ZnO films grown by pulsed laser deposition. Atomic force microscopy measurements show the existence of two growth regimes. Initially, the growth morphology is determined by shadowing effects due to the angular spreading of the plume in the 0.1 mbar oxygen working pressure. For longer deposition times a stepped pyramid-like structure is developed, whose roughening and coarsening behaviours are in agreement with those expected for growth systems with step-edge barriers.
