基本信息
General description【一般描述】
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.
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.
Application【应用】
  • Bioelectronics
  • FET based sensor research for active materials deposited on graphene
  • Clinical applications
  • Biosensors

GFET-S20 chip can be used as a biosensor and a chemical sensor for biological applications.
Features and Benefits【特点和优势】
