Location:
iSTEM Building 2, Room 1218

Developing efficient, room-temperature gamma-ray detectors is crucial for medical imaging, homeland security, and nuclear safety applications. Halide perovskites have emerged as promising materials for radiation detection due to their high stopping power, defect tolerance, and cost-effective fabrication. However, the performance of perovskite-based detectors is often limited by the presence of various defects, which degrade charge collection efficiency and energy resolution. This seminar explores recent advances in understanding and reducing the impact of defects in halide perovskite crystals, specifically focusing on structural, surface, and point defects.
