Resumo

The identification of single- and few-layer boron nitride is described. Its optical contrast is much smaller than that of graphene, but even monolayers are discernable by optimizing viewing conditions. The number of layers in thicker crystals can be counted by exploiting an integer-step increase in the Raman intensity and optical contrast.
