SUMMARY

The discussion centers on the feasibility of using the scotch tape method to produce hexagonal Boron Nitride (hBN) thin films from hBN powder with a maximum particle size of 10 micrometers. Participants confirm that while the scotch tape method can yield thin films, achieving dimensions larger than 10 micrometers is unlikely without compromising quality. Alternative methods such as atomic layer deposition (ALD) or chemical vapor deposition (CVD) are suggested for higher quality films. Additionally, inquiries about suppliers for high-quality hBN powders are raised.

PREREQUISITES
  • Understanding of the scotch tape method for thin film fabrication
  • Knowledge of hexagonal Boron Nitride (hBN) properties and applications
  • Familiarity with atomic layer deposition (ALD) and chemical vapor deposition (CVD) techniques
  • Awareness of suppliers for high-quality hBN powders
NEXT STEPS
  • Research the scotch tape method for producing hBN thin films
  • Explore atomic layer deposition (ALD) for high-quality thin film applications
  • Investigate chemical vapor deposition (CVD) techniques for hBN synthesis
  • Identify reputable suppliers of high-quality hBN powders
USEFUL FOR

Researchers, materials scientists, and engineers involved in thin film technology, particularly those focused on Boron Nitride applications and fabrication methods.

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.
 
I don't know about the scotch tape method (10 micrometers sounds pretty darn good to me, and if you get any that are larger, I expect it could be low quality/uneven surface compared to other methods). Does your institution have an atomic layer deposition or chemical deposition machines?
