Figure 5

Hydrogen sensor prototype and sensing response.

(a), The hydrogen prototype. (b), The ΔR response plots of NWs with screw-threaded shapes at 310.3 K. The temperature-dependence ΔR plots of (c) screw-threaded and (d) random-gapped PdCu NWs. The resistance modes, negative values (below Tc) corresponds to the RH (−) mode and positive ones to the RH (+) mode.
