Abstract
A high-sensitivity field effect transistor using as a channel ultrafine fiber elements such as carbon nanotube, and a biosensor using it. The field effect transistor comprises a substrate, a source electrode and a drain electrode arranged on the substrate, a channel for electrically connecting the source electrode with the drain electrode, and a gate electrode causing polarization due to the movement of free electrons in the substrate. For example, the substrate has a support substrate consisting of semiconductor or metal, a first insulating film formed on a first surface of the support substrate, and a second insulating film formed on a second surface of the support substrate, the source electrode, the drain electrode, and the channel arranged on the first insulating film, the gate electrode disposed on the second insulating film.
