Hydrogen gas sensing using a suspended carbon nanowire functionalized with palladium. Resistance change of a suspended carbon nanowire (width = 260 nm, thickness = 380 nm, length = 120 μm) functionalized with a palladium layer (thickness = 5 nm, length = 80 μm) in response to the concentration of hydrogen gas mixed with air was measured.
