衬底和样品信息： Graphene on Your Substrate - Processed in Clean Room Class 1000 This is a tailor made graphene product. You send your substrate to our laboratory (including your order ID and your email address as a reference) and we then use our innovative method to transfer the graphene monolayer on top of it and send it to the address you specify. Examples of substrates we have successfully transferred graphene to: devices, solar cells, LEDs, gold, alumina, silver mirrors and sapphire. Errors and sapphire.
