WebDec 1, 2009 · I trace back the origins of the famous Finnis-Sinclair potentials. These potentials mimic the results of tight binding theory through their use of the square root embedding function. From the tentative beginnings of tight binding in the 1930s up to 1984 or so, some of the famous names involved are Bloch, Seitz, Montroll, Friedel, Cyrot … Webmethod was extended to Finnis－Sinclair type potential problems using the effective pair－potential approximation． The rate of convergence was increased by over an order …
