Abstract:
We successfully fabricated MoS 2 photodetectors with different layers by sulfurization. It is found that the dark current increases with the number of layers. The three-layer MoS 2 photodetector has the largest response, which is 3.23 × 10 −6 A/W at 10 V. However, the current of the switching light was less than that of the previous cycle. It was presumed that the lifetime of the light-excited carriers was short, or more carriers would be trapped in the defects every cycle. For MoS 2 EGFET pH sensors, the sensitivity and linearity results showed that FSS performed better than on Si substrate with 200 nm SiO 2 . From the time-dependent response measurement, it was observed that the response of the two-layer MoS 2 EGFET pH sensors is very fast and stable, showing good reliability. In the future, MoS 2 sensors can be combined in different fields, such as biomedical science, agriculture, and fishery, for sensing applications and real-time monitoring.
