Custom Made Order
Custom Made Order Service Graphene Square has the capability to offer customized graphene synthesis for large sizes [up to meter scale] since we are a pioneer in large scale synthesis of graphene. Graphene Square is also able to provide a unique service by transferring graphene onto customers' own substrates, chips and materials. The process starts by the customer sending photo images and basic information about the target substrate material for initial feasibility review. Upon review, a test sample would be requested in order to do test transfer process at our headquarters. If the test transfer is successful, then the customer can send the required quantity of the same type of target substrate materials for the graphene transfer service.
Graphene Square's Strength

ㆍBi doping

This strong doping effect is stable enough to last for more than 10 months under ambient conditions due to the barrier properties of graphene covering the BI dopants. Also, graphene (BI graphene) showed excellent sheet resistance as low as ∼200 ohm/sq and high carrier concentration. Bi doping

ㆍDry transfer

If your substrate cannot go through a wet graphene transfer method based upon its solubility in water or in acetone, then the other option is Graphene Square's Dry transfer method. The first option is using our patented Thermal Release Tape [TRT] or the Pressure Sensitive Adhesive Film [PSAF]. Dry transfer
