Summary: | The crystal direction of CdS thin films produced by the laser ablation was
measured using X-ray diffractometer (XRD). The results reveal that the direction
of the CdS crystal depends considerably on the substrate temperature and laser
energy density. The
c
-axis of the CdS crystal changed from perpendicular to
parallel with the surface as the laser energy density increased. The parallality
of
c
-axis may be due to the clusters included in the laser plume. On the other
hand, the
c
-axis changed from parallel to perpendicular as the substrate
temperature increased. This phenomenon is considered to be that the clusters
on the substrate melting and re-crystallizing at the film surface due to the
high temperature prevailing during laser ablation. |
