explain GFET parameters
Answers
Explanation:
As the size and performance of silicon transistors approach their physical limits, there is a need to look for alternative materials to support emerging technologies. One of these materials being researched is graphene, which is an attractive channel material for field-effect transistors because of its superior electrical, mechanical, and thermal properties.
In this article, we'll talk about the basics of GFETs, including their construction, where they are superior to other field-effect transistors, and where they face challenges.
Defining a Graphene Transistor
The basic GFET is a three-terminal device that is similar to the conventional FET in some ways. It is composed of a source, drain, and a top or back gate. Unlike a silicon-based transistor, the GFET has a thin graphene channel, usually tens of microns thickness, between the source and drain metal electrodes.
