WebSep 13, 2006 · A modification is introduced to the original Finnis-Sinclair potentials for transition metals which substantially improves their pressure versus volume behaviour and overcomes their high-compression instability. With this modification good results are obtained for the energetics instability. With this modification good results are obtained for ... WebI 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 to 1984 or so, Bloch, Seitz, Montroll, Friedel, Cyrot-Lackmann and Ducastelle are some of the famous ...
