Abstract
Quantum chemical calculations on a model silicon lattice where combinations of interstitial p‐type dopant species (aluminum‐boron, aluminum‐gallium, and boron‐gallium) interact predict that all combinations will exhibit a pull effect. Diffusion of either member of a set will be retarded; the boron‐gallium pair will exhibit the greatest attraction between p‐type dopant pairs. There predictions are confirmed experimentally. Moreover, unanticipated enhanced electrical activity, greatly exceeding the additive, also is observed.
