An organic field-effect transistor is a field-effect transistor using an organic semiconductor in its channel.

A carbon nanotube field-effect transistor is a field-effect transistor that utilizes a single carbon nanotube or an array of carbon nanotubes as the channel material, instead of bulk silicon, as in the traditional MOSFET structure.

The tunnel field-effect transistor is an experimental type of transistor.

A ChemFET is a chemically-sensitive field-effect transistor, that is a field-effect transistor used as a sensor for measuring chemical concentrations in solution.
