Stress Enhancement of the G Line of Singly Ionized Zinc in Germanium

Abstract

Predictions of the relative intensities of stress-induced components of the D and G lines of Zn ? in germanium are compared with the experimental results. Striking disagreement is obtained if interaction is permitted between both pairs of appropriate adjacent substates of the final states of these two transitions. However,if the Zn - is allowed to be slightly displaced from the tetrahedral substitutional site and interaction is permitted between adjacent substates then the observations can be understood provided the displacement of the Zn - from its substitutional site increases with stress and the very weak G line is split even at zero stress.
