The goal of the project is to explore excitonic physics in a hybrid inorganic-organic system (HIOS) composed of transition metal dichalcogenide (TMDC) monolayers with a low-density molecular submonolayer deposited onto it. We will use the HIOS to i) probe trapping of TMDC excitons by localized molecule-induced electric and magnetic fields and ii) reveal dark excitons in TMDCs. We expect to develop a comprehensive understanding of interactions between individual donor, acceptor, dipolar, and magnetic molecules on one hand, and neutral, charged, defect-bound TMDC excitons on the other hand. Among potential applications of the HIOS studied here are electrically and chemically-tunable single photon emitters, highly sensitive molecule sensors, and photodetectors.

该项目的目标是探索由过渡金属二卤化物(TMDC)单分子膜和沉积在其上的低密度分子亚单层组成的无机-有机混合体系(HIO)中的激子物理。我们将利用HIOS来探测分子诱导的电场和磁场对TMDC激子的捕获，以及II)揭示TMDDC中的暗激子。我们期望对单个施主、受主、偶极和磁性分子与中性、带电、缺陷束缚的TMDC激子之间的相互作用有一个全面的理解。在这里研究的HIO的潜在应用包括电子和化学可调谐的单光子发射器、高灵敏度的分子传感器和光电探测器。
