| Outline of Final Research Achievements |
We have developed a unique growth technique based on MOCVD method to synthesize transition metal dichalcogenide monolayers, which are promising new semiconductors in next generation. The potential and functionality of these materials were studied from the viewpoint of photonic applications. We showed that Mo- and W-oxychlorides are appropriate precursors in MOCVD growth, and also found that an alkaline aluminosilicate glass is useful as the growth substrate because it has both high heat resistance and efficient catalytic effect. To explore heterostructures and quantum nanostrucures of TMDC, we realized expanding the material variations of TMDC which can be grown by MOCVD, and succeeded in observing in-plane quantum confinement effect for the first time.
