Field Effect Transistor (Glossary of Printed Electronic terms)

For decades there has been research on transistors that can be deposited on surfaces and are very thin. These transistors are all so-called Field Effect Transistors (FETs) because this construction consists of thin films rather than the alternative, so-called bipolar transistors which require diffusion of "dopants" into a substrate.
