Abstract At the beginning of this seminar, I will give a brief overview of the Consortium for Enabling Technologies and Innovation that has been sponsored by DOE NNSA since 2019, as well as the recently awarded ETI2.0. Then, I will present our recent research progress in the development of high-performance silicon photomultipliers also known as SiPM for nuclear nonproliferation. SiPM has become very attractive in many application fields to detect light with very low intensity, including ionizing radiation detection, biomedical imaging, and light detection and ranging (LiDAR) for autonomous driving. However, the peak value of photon detection efficiency of conventional SiPM is still limited. Among the efficiency limiting factors are avalanche triggering probability, geometrical fill factor due to dead areas, and quantum efficiency. Therefore, our research focus on three technical approaches for increasing the photon detection efficiency of SiPM, advanced antireflection feature, superior silicon surface passivation, and novel back-illuminated device structure. |

Biography Dr. Yuguo Tao is a Senior Research Engineer at Nuclear and Radiological Engineering and Medical Physics at Georgia Tech, focusing on the development of advanced radiation detectors for nuclear nonproliferation at Laboratory for Advanced Nuclear Nonproliferation and Safety that is led by Prof. Anna Erickson. Prior to joining the LANNS group, Dr. Tao was a Research Engineer at the School of Electrical and Computer Engineering at Georgia Tech to develop high-efficiency cost-effective silicon solar cells for renewable energy applications. Dr. Tao graduated from University of New South Wales in Australia with a PhD in Photovoltaic Engineering in 2012, and from Tianjin University in China with a M.S. degree in Power Machinery and Engineering in 2005 and a B.S. degree in Mechanical Engineering in 2002. He also had 3-year experience in working at the R&D department at Bosch and then SIEMENS in automotive industry after his M.S. study. |
