摘要：

Several hydrogen-vibrational lines have been discovered near 1800 cm(-1) in Si that contains Au and H. These hydrogen-stretching lines are assigned to AuH, FeAuH, and AuH2 complexes. The AuH and FeAuH complexes were found to be electrically active with the different charge states having vibrational frequencies shifted by ca. 15 cm(-1). The antisymmetric and symmetric stretching modes of one charge state of AuH2 have been assigned. Tentative structural models for the complexes are proposed. These results show that the complexes containing Au and H have properties similar to PW and PtH2 complexes studied previously. (C) 1999 Published by Elsevier Science S.A. AU rights reserved.
