GFET chips offer scientists direct access to the most recent graphene devices. This supports application-driven research by eliminating the need to develop GFETs from scratch. Each chip includes 36 individual GFETs distributed in distinctive patterns—06-2555: Grid pattern; 06-2560: Quadrant pattern.
Features
- 36 individual GFETs per chip
- Devices not encapsulated ready for customers’ functionalization
- Mobilities typically in excess of 1000 cm2/V.s
- Ideal platform device for the research and development of new sensors
Applications
- Graphene device research
- Bioelectronics
- Chemical sensors
- Magnetic sensors
- Biosensors
- Photodetectors
