Spectroscopic mapping of local electronic/thermoelectric properties

了解有机材料在小尺度上的电荷和热传递对于揭示这些系统的输运物理具有重要意义。电荷调制显微镜是研究这些性质的一种强有力的技术。这将需要建立一个新的测量系统，与我们现有的电荷调制光谱设置相比，该系统可以加快信号采集并提高信噪比。我对在有机热电材料中使用时间分辨显微镜也很感兴趣。时间分辨热传递测量将在Akshay小组现有的显微镜装置上进行。

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.
