Friedrich-AlexanderUniversität Erlangen-Nürnberg(FAU)

主讲人简介:

He obtained Bachelor’s and Master’s degrees in Materials Science from Hunan University, China, and Doctor degree (summa cum laude) in Experimental Physics from Humboldt-Universitaet zu Berlin in 2014. He is an enthusiastic“nano-photographer”with over 15 years of experience in electron microscopy. His expertise lies in developing and applying advanced microscopy, diffraction, and spectroscopy techniques—integrated with in situ, operando, and data science approaches—to gain unique insights into modern functional materials. He has published ~80 peer reviewed articles. In 2023, he received the“Outstanding Paper Award”from European Microscopy Society for contribution of developing 4D-STEM method for organic solar cell materials.

讲座摘要:

In this talk, I will report our efforts toward systematically and correlatively characterize the structure of OSCs and organic semiconductor thin films using TEM: from nano-morphology of OSC using analytical methods (with energy-filtered TEM or spatially resolved electron energy-loss spectroscopy), to evaluating their texture with EF-SAED (energy-filtered selection area electron diffraction) and 3D electron diffraction. The results are compared to that from identical sample using established X-ray based method using lab and synchrotron sources. Finally I will showcase probing local structure information with our recently proposed, dose-efficient method 4D-scanning confocal electron diffraction (4D-SCED) technique .
