GFET-S11 for Sensing applications

GFET-S11 for Sensing applications

Product Details:


Product Description

GFET-S11 (Die size 10 mm x 10 mm) - Processed in Clean Room Class 1000

The GFET-S11 chip from Graphenea provides 31 graphene devices with a van der Pauw (vdP) geometry, distributed in 3 different sizes. 3 vdPs have a 2x2mm2 footprint, 14 vdPs have a 500x500m2 footprint and 14 vdPs have a 125x125m2 footprint. These devices have an optimized geometry for 4-probe measurements in a vdP configuration. These varying graphene device dimensions allow investigation of geometry dependence on device properties, enabling immediate optimization.
