Abstract

We examine the effect of boron doping in superconducting forms of amorphous carbon. By judiciously optimizing boron substitutional sites in simulated amorphous carbon we predict a superconducting transition temperature near 37 K at 14 % boron concentration. Our findings have direct implications for understanding the recently discovered high T_$c$ superconductivity in Q-carbon.
