General description

Roll-to-roll, high-quality, monolayer CVD graphene with large grain size (∼110μm2) on 4 inch silicon wafer.

Application

Our Roll-to-Roll CVD graphene products are true monolayer high quality graphene, fabricated inside a Cleanroom, heavily monitored and QC to assure high reproducibility.
The roll-to-roll process allows continuous, large scale graphene production.
This large grain size graphene product on silicon wafer is ready to use, helps you minimize process time, and increase success rate. This product with low sheet resistance would enable unmatched reproducibility and allow high performance for CVD graphene based FET, CVD graphene based sensors, and heterostructure based micro/nano electronics.

Application examples:
  • Ultrafast Transistor
  • Optical devices
  • Bio/Gas Sensor
  • Transparent Electrode
  • Flexible Display
  • Smart Coating
  • Thermal management

Caution

Be cautious not to drop
Keep away from contamination, heat, dust and flame etc.

Storage and Stability

Avoid direct sun light, avoid high temperature, avoid high humidity, and avoid dust.
