Crystalline boron nitride nanosheets by sonication-assisted hydrothermal exfoliation
Abstract A simple method to prepare two-dimensional hexagonal boron nitride (h-BN) scalably is essential for practical applications. Despite intense research in this area, high-yield production of two-dimensional h-BN with large size and high crystallinity is still a key challenge. In the present wo...
