| Outline of Final Research Achievements |
Direct bandgap and unique electronic structure in monolayer transition metal dichalcogenides (TMDCs) provides a platform for exploring novel valley functionalities optoelectronic functionalities. In this proposal, we fabricated large-area sample and developed the electrochemical method to dope both holes and electrons. Finally, we performed several valley functionalities, such as (i) electric-field induced metal-insulator transition, (ii) circularly polarized EL emission, and (iii) optimization of thermopower conversion efficiency.
