Abstract:
An NO2 detection device (200) includes a substrate (102/104); a drain (112) formed on the substrate (102/104); a source (114) formed on the substrate (102/104); a p-type polymer semiconductor layer (110) formed on the substrate (102/104), between the drain (112) and the source (114); and an n-type metal-organic framework layer (120) located over the p-type polymer semiconductor layer (110). The n-type metal-organic framework layer (120) has apertures (122) having a size larger than a size of the NO2 molecules so that the NO2 molecules pass through the n-type metal-organic framework layer (120) to arrive at the p-type polymer semiconductor layer (110) to increase an electrical current.
