1. A gas detector for detecting benzene, toluene, ethylbenzene or xylene (a BTEX gas), the detector comprising at least one transducer comprising:
a field effect transistor (FET) comprising a source electrode, a gate electrode, and a drain electrode;
at least one silicon nanowire with a native oxide shell layer, the at least one silicon nanowire extending and coupled between the source electrode and the drain electrode; and
an arene compound, wherein the arene compound is disposed on the at least one silicon nanowire and is configured to capture a BTEX gas,
wherein an electronic characteristic of the transducer changes when a BTEX gas is captured by the arene compound.
