Multi-million-atom tight-binding simulations are performed to understand the measured decrease in $| \\Delta g |$ as a function of $x$, which is attributed to a reduction in the interface-related anisotropy. For $x <$7\\%, the variation in $| \\Delta g |$ is linear and can be described by $\\eta_x x$, where $\\eta_x \\approx$1.62$\\times$ 10$^{-3}$. At $x$=20\\%, the measured $| \\Delta g |$ is 1.","authors_text":"A. R. Stegner, C. D. Hill, H. Huebl, L. C. L. Hollenberg, M. S. Brandt, M.
