摘要: We have performed Co K-edge x-ray absorption fine structure and near edge measurements of Co-doped plasma enhanced chemical vapor phase deposition (PECVD) grown “C2B10Hx” semiconducting boron carbides, using cobaltocene. Cobalt does not dope PECVD carbides as a random fragment the cobaltocene source gas. The atoms are fivefold coordinated (R=2.10±0.02A) chemically bonded to icosahedral cages B10CHx or B9C2Hy. Pairwise doping occurs, with cobalt favoring sites some 5.28±0.02A apart.
