“…It is highly urgent to search for more intrinsic TSC candidates with high superconducting critical temperature ( T c ) and topological surface states near E F . In recent, some strong candidates for TSC have been found in compounds formed by the IVA group elements and metals, such as AuSn 4 , [ 23 , 24 ] Au 2 Pb, [ 25 ] PtPb 4 , [ 26 ] Ta 3 (Sn, Pb), [ 27 ] BaSn 5 , [ 28 ] (Ta, Nb)RuSi, [ 29 ] and binary transition‐metal carbides (TMCs). [ 30 , 31 , 32 , 33 , 34 ] Among these TSCs, TMCs have a relatively high T c .…”
