We describe the fabrication of nanostructures on SiGe film by KrF excimer laser with nanosecond pulse width, and find a more direct and clear relationship between the laser irradiation conditions and the nanoscale structures. Perfect annular nanostructures around scattering points on the SiGe film are firstly obtained after the irradiation of a KrF excimer pulse laser beam (100 mJ/cm(2)) at different incident angles. The different shapes of annular structures are related to different energy distributions due to the optical interference between the scattered light and the incident beam. As laser energy increases, a threshold of pulse energy (230 mJ/cm(2)) is found, above which a droplet-like morphology completely replacing the surface annular structures. And the disorder morphology is mainly caused by the thermal effect of the incident beam.
