| Research Abstract |
In this study, gravity assisted pulsed laser ablation(GAPLA) method is used to fabricate a compositional gradient thin film which consists of low melting point material. Although a composition gradient effect became smaller than the case of high melting point material, it turned out that the GAPLA method is effective also in the composition gradient of low melting point material. Furthermore, it became clear that the composition gradient process by the GAPLA method is not based on diffusion theory. This result means that there is almost no relation of the melting point of material and the composition gradient effect. However, it is acquired an important knowledge that the degree of composition gradient is decided by the difference in ablation characteristic of each constituent element.
