A suspended semiconductor nanowire, which exhibits high sensitivity to SO2 (119% in 0.5 ppm) at room temperature, is reported by Yichun Liu, Qingxin Tang and co‐workers on page 2269. This configuration allows the detected gas to make direct contact with the semiconductor/dielectric interface where the charge transport takes place. The back cover shows the adsorption of SO2 at the bottom of the transparent...
A room‐temperature highly‐sensitive SO2 sensor with fast response and complete recovery is constructed based on gas dielectric field‐effect transistor (FET) of CuPc single crystalline nanowire. The exposed conductive channel by gas dielectric is responsible for the high sensitivity to SO2 and the adsorption of the SO2 molecules dramatically enhances the field‐effect mobility. These results not only...
