Hexagonal boron nitride: a review on selfstanding crystals synthesis towards 2D nanosheets [16-12-2021]
Hexagonal boron nitride (hBN) is emerging as essential for 2D material-based technologies. New optoelectronic applications require high crystal quality hBN with low defect density and contamination. While vapor-phase processes like chemical vapor deposition can produce large-area hBN thin films, self-standing hexagonal boron nitride crystals provide exfoliated nanosheets of very high quality.
