Article Synopsis
- Transition-metal sulfides, particularly CuS, are being recognized as strong candidates for gas sensors, moving away from traditional metal oxides.
- A novel method was developed to create a flexible, semitransparent NH gas sensor featuring an ultrathin CuS layer, with its properties optimized by adjusting copper film thickness and sulfurization time.
- The CuS sensor shows high sensitivity with a detection limit of 1.38 ppm for NH gas at 150 °C, and offers mechanical durability and visibility in light applications.
