| Outline of Final Research Achievements |
In this study, we investigated new chalcopyrite compounds in order to improve surface morphology of ZnSnP2 thin films. It was clarified that CdSnP2 is a potential material, while compounds including Mg or Ca are reactive with atmospheric water vapor.The bandgap can be controlled with composition using solid-solution of ZnSnP2-CdSnP2. For fabrication of thin films, we successfully obtained CdSnP2 films by phosphidation of Cd-Sn precursors, however formation of films with solid-solution were not achieved, which was one of the purposes in this study.
In another topic, it was demonstrated that pn junction could be formed utilizing the interface between ZnSnP2 and CdSnP2, which were p-type and n-type conductivity, respectively. Such a junction can lead to new devices.
