Research Impact & Significance – h-BN is a layered material with could be exfoliated by scotch tape. Under the optical microscope, the crystals on the substrate display various colors due to optical contrast according to the thickness of crystals. Given this characteristic, we could select the crystals of interested thickness based on the contrast color, which is a very important step for nano-device fabrication.
