WebSep 2, 2024 · The methods with lower LOD than these methods were reported, such as Tu, where it was reported that the LOD was 40 pM using a liquid-gated graphene field-effect transistor (FET) . Guo et al. reported a fluorescent sensor for Hg 2+ detection and LOD was 0.17 nM using the acridine orange (AO) [ 37 ]. WebJan 29, 2024 · Finally, we calculated the carrier mobility in the as-fabricated monolayer graphene FET. To do so, we extracted the channel resistivity of device 1 from the slope of the linear regressions in Fig. 3(b) at different carrier densities. Figure 3(d) shows the plot of ρ ch against the carrier density in graphene.
