Outline of Final Research Achievements

The purpose of this proposal was to realize high-performance and functional light-emitting devices of atomically thin transition metal dichalcogenides (TMDCs) with electrolyte-based device structures. To achieve this goal, first, we fabricated light-emitting devices with various TMDCs and their heterostructures. We evaluated fundamental optical properties with wide-range (VIS-NIR) light emission spectra in these devices. Second, we established solution-based transferred methods and build the devices on the plastic substrates, resulting in highly flexible TMDC light-emitting devices. Finally, we also tried to embed the cavity structure inside light-emitting devices to enhance their efficiency. Furthermore, we found out a unique origin to realize circularly polarized light-emitting devices in TMDCs, which will open new pathways for exploring new functional optoelectronic devices based on atomically thin TMDCs.

Academic Significance and Societal Importance of the Research Achievements

原子層遷移金属ダイカルコゲナイド(TMDC)は低次元系特有の光物性と多彩な発光色、優れた可塑性を有しており、Internet of Thingsを体現する次世代光デバイスを担う材料であると期待されている。しかしながら、従来のTMDCを用いた発光デバイス作製技術は汎用性に乏しく、高機能化や高性能化の研究は皆無であった。これに対し、本研究では独自の素子技術を開発することで様々なTMDC発光デバイスを容易に作製でき、高柔軟性や共振器導入可能なデバイスを実現した。ここで構築した素子技術及び材料物性はTMDCの光デバイス応用へのベンチマークを築くものであり、その学術的・産業的インパクトは極めて大きい。
