Our 25 micron-thick copper foil is sourced from a reliable, quality-assured supplier in the United States. As part of our commitment to delivering the highest quality graphene at affordable prices, our in house substrate processing results in copper grain sizes that are tens of square centimeters in area.
3” x 3” hBN/copper foil pieces are secured to their underlying plastic containers with four small Kapton tapes, one in each corner. Gently peel the tape or cut off the corners of the foil to release the foil from the plastic container.
Do you need assistance with Raman measurements on your custom/modified hBN sample? We can help! Please inquire at support@Grolltex.com or call (858) 368-9065 for details.
*The indicated product metrics are generic to our transfer process. For all hBN-on-copper products, the displayed range represents electronic data that we have obtained using our in-house transfer capabilities to transfer hBN to SiO2. Your own metrics will depend entirely on the transfer methods that you use, and the resultant quality of your transfers.
Data files for Raman measurements are available upon request. Please send an email including your name, institution, and product serial number to firstname.lastname@example.org and indicate which file(s) you would like.
The best tools for cutting your graphene foil are a rubberized cutting mat and a rotary cutting blade, or a sharp scalpel. Please recycle the plastic case when no longer needed!
Please keep the product serial number you receive with your sample, as it will assist us if you have inquiries about the product. The serial number (S/N) is located on the clear plastic container the graphene arrives in, the external silver bag, and your packing list.
