abstract = {<p style="text-align: justify;">Crystalline and amorphous $BC_2N$ supercells with 216 atoms 
have been constructed by random distributions of $B,$ $C,$ and $N$ atoms in the diamond lattice and amorphous sp$^3$ carbon 
structure, respectively. The atomic structures of these two 
systems were relaxed using density functional theory, and 
their mechanical properties including the bulk modulus, shear 
modulus, and Young&#39;s modulus were computed. Crystalline $BC_2N$ possess higher elastic moduli than those of cubic $BN.$ Amorphous $BC_2N$ exhibit reasonable elastic moduli and 
appreciable ductility with a large ratio between the bulk 
modulus and shear modulus. Both crystalline and amorphous $BC_2N$ are superior candidates as superhard materials.</p>},
