Understanding the charge and heat transfer of organic materials down to small length scales are important to reveal the transport physics of these systems. Charge modulation microscopy is a powerful technique to investigate these properties with high spatial solution. This will require setting up a new measurement system that speeds up the signal acquisition and improves the signal-to-noise ratio compared to our existing charge modulation spectroscopy setup. I'm also interested in using time-resolved microscopy in organic thermoelectric materials. The time-resolved heat transport measurement will be performed on an existing microscopy setup in Akshay's group.

了解有机材料的电荷和传热至较小的尺度对于揭示这些系统的传输物理非常重要。电荷调制显微镜是一种使用高空间溶液研究这些特性的强大技术。这将需要建立一个新的测量系统，以加快信号采集的速度并与我们现有的电荷调制光谱设置相比，提高信号噪声比率。我也有兴趣在有机热电材料中使用时间分辨显微镜。时间分辨的热传输测量将在Akshay组的现有显微镜设置上进行。
