Time-, momentum-, and energy-resolved dynamics of excitons and phonons in TMDC/organic hybrids (B17*)

该项目的中心目标是获得TMDC-有机（TMDC：过渡金属二硫化物）无机/有机杂化体系（HIOS）中电子和振动激发的微观理解。我们将用时间和角度分辨光电子能谱作为飞秒电子衍射的相关结构动力学，在四个维度（能量、动量、时间）上研究激子的动力学。我们的目标是确定控制微观能量和电荷流动的主要机制，并量化激子-声子耦合和能量耗散等基本现象。

The central goal of project is to obtain a microscopic understanding of electronic and vibrational excitations in TMDC-organic (TMDC: transition metal dichalcogenide) hybrid inorganic/organic systems (HIOS). We will study the dynamics of excitons in four dimensions (energy, momentum, time) with time- and angle-resolved photoelectron spectroscopy as the associated structural dynamics with femtosecond electron diffraction. We aim to identify the dominating mechanisms governing microscopic energy and charge flow and to quantify basic phenomena like exciton-phonon coupling and energy dissipation.
