description | In this study, we show a direct correlation between the applied mechanical strain and an increase in monolayer MoS
photoresponsivity. This shows that tensile strain can improve the efficiency of monolayer MoS
photodetectors. The observed high photocurrent and extended response time in our devices are indicative that devices are predominantly governed by photogating mechanisms, which become more prominent with applied tensile strain. Furthermore, we have demonstrated that a nonencapsulated MoS
monolayer can be used in strain-based devices for many cycles and extensive periods of time, showing endurance under ambient conditions without loss of functionality. Such robustness emphasizes the potential of MoS
for further functionalization and utilization of different flexible sensors. |
