Perovskites for radiation detection and imaging - from materials to devices

Abstract: Radiation detection sees a wide application in various fields, where the novel materials and device fabrication technologies always play a central role. The limitations of the current detectors, such as cost, performance, or flexibility, have continued to drive the discovery and development of new materials. In recent years, metal halide perovskites emerged with a promising performance for next-generation radiation detectors that can be used for gamma spectroscopy, X-ray detection, neutron detection, and radiation imaging. 

In this seminar, I will be presenting my research on perovskite radiation detectors, which covers a broad spectrum, including 1) perovskite material growth, synthesis, and characterization, 2) device physics/structure analysis, device design and fabrication, 3) radiation detection performance testing and improvement, 4) detector applications in medical imaging and scientific research. Furthermore, I will introduce my work on a Digital Pulse Processing (DPP) algorithm for perovskite detector signal processing. These results contribute to the development of novel materials, sensors, and their applications in radiation detection. 

Bio: Dr. Lei Pan received his B.S. (2014) and Master degree (2017) in Nuclear Science and Technology from University of Science and Technology of China. He earned his PhD in Nuclear Engineering from The Ohio State University under the guidance of Prof. Raymond Cao in 2021. His PhD thesis focuses on device design, fabrication and testing of perovskites, an emerging new class of materials, as high-performance semiconductor X-ray, gamma-ray, and neutron detectors. Following his PhD, Lei moved to Northwestern University working with Prof. Mercouri Kanatzidis in Department of Chemistry to develop various novel materials for radiation detection. At Northwestern, Lei’s work extends to material engineering with expertise gained in material synthesis and characterization. Meanwhile, Lei builds up his industry experience involving with a startup company developing radiation imaging techniques. Recently, Lei joined the Applied Nuclear Physics program at Lawrence Berkeley National Lab, where he works on developing advanced radiation detection systems that include both instrumentation and software development. 

Dr. Lei Pan has published 13 journal articles (8 first-authored), 2 conference proceedings, 1 book chapter (first author), filed 2 patents, with several more papers under review or being prepared. Lei’s research interests lie in the interdisciplinary area of Nuclear, Material and Electrical engineering, which revolves around radiation detection and their applications in medical imaging, nuclear energy, nuclear non-proliferation, and scientific research.
