摘要：

Local vibrational modes of a carbon-hydrogen complex have been identified with infrared absorption spectroscopy. After implantation of protons or deuterons at approximate to 20 K a carbon mode at 596 cm(-1) and a hydrogen mode at 1884 cm(-1) are observed in the sample annealed at 180 K. The two modes originate from the same defect, which is tentatively identified as bond centred hydrogen in the vicinity of a nearby substitutional carbon atom. (C) 1999 Elsevier Science S.A.
