Hi there, I am preparing to use the scotch tape method to get hex-Boron Nitride thin film from hBN powder. As far as I know, the available particle size for hBN is 10 um at most, is it possible for me to get hBN thin film using the peel off method with size larger than 10 um? If so, what is the largest possible dimension I can get? If not, how about peel off the hBN sheet to get hBN thin film? Also, I will appreciate if anyone could tell me which company can provide very high quality hBN powders. Thanks in advance.
