Product Description

GFET-S10 (Die size 10 mm x 10 mm) - Processed in Clean Room Class 1000

The GFET-S10 chip from Graphenea provides 36 graphene devices distributed in a grid pattern on the chip.  Thirty devices have a Hall-bar geometry and six have a 2-probe geometry.  The Hall-bar devices can be used for Hall-bar measurements as well as 4-probe and 2-probe devices.  There are varying graphene channel dimensions to allow investigation of geometry dependence on device properties.

The new version replaces Ni/Al contacts by Cr/Au, which are more inert and stable.
