Simulating the effect of boron doping in superconducting carbon

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.
