Because of their unique physical, chemical, electrical
and optical properties, two-dimensional (2-D) materials have
attracted tremendous attention in the past decades. After revealing
the realistic strength and stretchability of graphene, nicknamed
“black gold,” researchers from City University of Hong Kong (CityU)
have carried forward the success by unveiling the high defect
tolerance and elasticity of hexagonal boron nitride (h-BN), another
2-D material known as “white graphene.” This follow-up study will
promote future development and applications of strain engineering,
piezoelectronics and flexible electronics.
