Sensors: Gas Dielectric Transistor of CuPc Single Crystalline Nanowire for SO2 Detection Down to Sub-ppm Levels at Room Temperature (Adv. Mater. 16/2013)
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 nanowire, allowing high-sensitivity room-temperature SO2 detection.
