High-Performance CsPbI₃ Quantum Dot Photodetector with a Vertical Structure Based on the Frenkel–Poole Emission Effect

This is the authors' abstract. We don't add key points for this paper.

The selection of photoactive materials and the design of device structures are critical to the photoelectronic performance of photodetectors. This study reports on a vertically structured photodetector device with rapid, stable, and efficient photoelectric performance across the UV-visible broadband range based on the Si
