Tight-Binding parameters for Tin


Tin (Sn)
Atomic Number 50
Atomic Weight 118.710
Room Temperature Structure diamond (A4)
Experimental Lattice Constant a 0.582 nm

The s and p tight-binding parameters were fit to first-principles Linearized Augmented Plane Wave (LAPW) results. The d orbitals were excluded from the fit. We have two parametrizations for Tin. Their behavior is outlined in the paper: Tight-binding description of the electronic structure and total energy of tin, Phil. Mag. B 82, 47-61 (2002).

Sn Case-1 Parameters Suitable for Electronic Structure Evaluation
