The aim of this project is to observe and harness the dynamics of the excited state in molecular and nanocrystal-based electronic materials and devices. The project will involve the development of a novel experimental system, which will use ultrafast IR light pulses to control the electronic dynamics of the excited state and vibrational motions of the molecules inside the active layer of the nanodevices. The effect of the low-energy optical excitation on the performance of the devices will be evaluated to uncover various fundamental aspects of charge dynamics and how these aspects can be used in molecular/plastic electronic applications. The results of this work will be instrumental in improving the functionality of molecular and quantum dot nanomaterials and optoelectronic systems.

这个项目的目的是观察和利用分子和纳米晶基电子材料和器件中激发态的动力学。该项目将涉及开发一种新的实验系统，该系统将使用超快红外光脉冲来控制纳米器件活性层内分子的激发态和振动运动的电子动力学。将评估低能光激发对器件性能的影响，以揭示电荷动力学的各个基本方面，以及如何将这些方面用于分子/塑料电子应用。这项工作的结果将有助于提高分子和量子点纳米材料和光电子系统的功能。
