Description générale

Device configuration:

This Graphene FET chip provides 36 graphene devices distributed in a grid pattern on the chip. 30 devices have Hall-bar geometry and 6 have 2-probe geometry.
The Hall-bar devices can be used for Hall measurements as well as 4-probe and 2-probe measurements. There are graphene channels with varied dimensions to allow systematic investigation of device properties.
Graphene FET chip (GFET-S10 chip) is a graphene based field effect transistor chip with a symmetric transconductance of 8 μS and an operational current density of 105 A/cm2. The fabricated device has a monolayered graphene which is coated by chemical vapor deposition (CVD) on silicon substrate. It also has similar gate insulators in the source and drain.

Application

  • Graphene device research
  • FET based sensor research for active materials deposited on graphene
  • Chemical sensors
  • Biosensors
  • Bioelectronics
  • Magnetic sensors
  • Photodetectors
GFET-S10 chip can be used as a biosensor and a chemical sensor for biological applications.

Caractéristiques et avantages

Device Features:

  • State-of-art graphene FETs utilizing consistent high-quality CVD grown monolayer graphene
  • Devices are not encapsulated and can be functionalized by additives
  • Perfect platform for sensor research and development
  • 36 individual graphene FETs per chip
