Outline of Final Research Achievements

We tried to investigate the applicability of molecular materials for improvement of inorganic device materials. In this research, as inorganic device materials, we focused on germanium and 2D semiconducting materials. We applied molecular treatment mainly using superacid and investigated how it works and improves the properties of the inorganic device materials. We clarified that solvents which dissolve molecules are important for improving the device performance after the molecular treatment. Our investigation would be useful for applying the next generation inorganic materials for electro-optical devices and extracting the potential properties by chemical treatment.
