Abstract
A solid-state field-effect transistor device for detecting chemical and biological species and for detecting changes in radiation is disclosed. The device includes a quantum wire channel section to improve device sensitivity. The device is operated in a fully depleted mode such that a sensed biological, chemical or radiation change causes an exponential change in channel conductance of the transistor.
