Boron carbon nitride is another layered material of the carbon family, which have similar structural, mechanical, electrical and thermal properties as that of graphene doped with B and N, and has gained intense research consideration over the past few years. The 2D hexagonal boron nitride (hBN) has similar geometry to graphene, wherein the carbon atoms at vertices of the planar hexagonal sp 2 network is substituted by boron and nitrogen atoms, and the van der Waals forces pull adjacent hBN layers together . Being the neighbours of C in the periodic table, B and N have similar atomic radii (B: 87 pm, C: 67 pm, and N: 56 pm), but with distinguished electronegativity values (B: 2.04, C: 2.55, and N: 3.04). The huge difference in the electronegativity values of B and N, forms highly polarized covalent bonds, and brings out partial ionic feature, and electrical insulation with an indirect band of 5. . The integration of graphene with hBN has modulated the hBN bandgap effectively, due to the doping of carbon atoms into the hBN lattice and results in the formation of BCN layers. The hybrid compounds made of three elements boron, carbon, and nitride are attractive due to the expectation of intermediate or even better qualities, in comparison to C and BN, which has the computed direct bandgap of 1.18 eV for BCN monolayer . Boron carbon nitride is a ternary compound composed of boron, carbon, and nitrogen atoms that indwell the positions of graphene in a 2D structure. BCN may be further classified into simple, and complex structure ranging from B-N and C-C (graphene) domains containing composites to B-C and C-N bonds along with B-N and C-C bonding. The structure of BCN is anticipated to possess properties from being an insulating material (boron nitride) to a conducting material (graphene) .
