Superconductivity in heavily boron-doped silicon carbide
2009/1/28· The unreacted silicon in our samples is likely to be an insulating phase fraction with no electronic and almost no phononic contributions to the specific heat at low temperatures. Therefore, a residual contribution caused by this phase fraction cannot easily explain the values for γ res found in the specific-heat analysis assuming a BCS-like scenario given in [ 11 , 15 ], as mentioned in the
