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 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 support@Grolltex.com and indicate which file(s) you would like.

Tips Safety Data Sheet

  • To ensure the maximum shelf life of your hBN sample, it is best stored under vacuum or in inert atmosphere (Argon or Nitrogen) conditions once the vacuum sealed package has been opened.
  • 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.

  • We have taken the guesswork out of your project by analyzing every piece of hBN that leaves the door. Take advantage of the data files available for your hBN batch. Contact us if you require additional characterization of your hBN.
  • If you are planning to perform any patterning or post-processing on your wafer, it is recommended that you perform a wafer conditioning step no more than 12 hours prior to post-processing. Please contact us for recommendations that suit your substrate material.
