High-performance foldable and flexible photodetectors are crucial for advanced electronics and AR/VR tech.
A novel method using a backside Al metal mirror significantly boosts the photocurrent in a molybdenum disulfide (MoS) photodetector when folded.
The addition of the Al mirror improved photocurrent from 4.04 μA to 8.53 μA, enhancing efficiency in both folded states, which could benefit future foldable electronic devices.
