Abstract
Methods and apparatuses for detecting ammonia are disclosed. A sensor can include a transistor having a gate, a drain, and a source. A layer of ammonia detecting material can be functionally attached to the transistor. The ammonia detecting material can be zinc oxide (ZnO) nanorods, which effectively functionalize the transistor by changing the amount of current that flows through the gate when a voltage is applied. Alternatively, or in addition to ZnO nanorods, films or nanostructure type metal oxides including TiO2, ITO, ZnO, WOand AZO can be used. The transistor is preferably a high electron mobility transistor (HEMT).
