Description

General description

Device configuration:

The graphene FET-S20 chip is designed for measurements in liquid medium. This chip provides 12 graphene devices, with encapsulation on the metal pads to avoid degradation and reduce leakage currents, and the probe pads located near the periphery of the chip. It also includes a non-encapsulated electrode at the center of the chip, which allows liquid gating without the need of an external gate electrode.

Graphene FET chip (GFET-S20 chip) is a graphene based field effect transistor which can be coated on silicon substrate by atmospheric pressure chemical vapor deposition (CVD). It also has similar gate insulators in the source and drain.
