Abstract

A different Pd-related defect from a substitutional Pd with (C_2v) symmetry was detected by ESR measurement. New ESR signal of the Pd-related defect showed different g-value and symmetry from those of the substitutional Pd. The Pd-related defect has anisotropic character of monoclinic (C_1h) symmetry. The calculated g-values are g₁=1.97, g₂=2.03, g₃=2.16, and the g₁ axis is along 〈1 1 0〉 direction. The g₂ and g₃ axes are perpendicular to the g₁ axis, and the g₂ axis is rotated from 〈1 0 0〉 to 〈1 1 1〉 direction at the angle of 51°. In addition to the Pd-related defect, we have found other ESR signals in Pd and hydrogen-diffused Si. The ESR signals showed the hyperfine structure of hydrogen. Therefore, it is though that the ESR signals are originated from Pd-H complex defect.
