New Semiconductor Devices for Dark Matter Detection

Abstract

Dark matter remains a fundamental mystery in particle physics, and extensive efforts have been made to detect it in labs. In this talk, the speaker will summarize the recent progress in sub-GeV dark matter detection with semiconductors and introduce our new idea to probe sub-MeV dark matter with doped semiconductors. He will also discuss the origin of the unexplored backgrounds in current detectors and demonstrate our dual-sided CCD design can significantly reduce some those backgrounds.

About the Speaker

Dr. DU Peizhi has been a postdoc at Rutgers University since 2022. He received his PhD from the University of Maryland in 2019 and then moved to Stony Brook University for his first postdoc position (2019-2022). His research focuses on theoretical particle physics and cosmology, including dark matter direct detection, constraining new physics in astrophysics and cosmology, and cosmological phase transitions.
