Dear Netters, Can someone point me to programs available for calculating electronic band structures in 1-, 2-, and 3- dimensions? I remember a few years back that a program known as VEH (Valence Effective Hamiltonian) was capable of doing this, but there may be others (or updated versions of VEH). I would be interested in both semi-empirical and ab initio programs. Thanks ... Prof. Bill Welsh Dept. of Chemistry University of Missouri-St. Louis
