  1. Electron poor materials research group Group meeting Dec 16, 2010 Theory- NaCl - Bader tests. What does a very ionic structure look like?

  2. Procedure • A NaCl example can be downloaded from: http://theory.cm.utexas.edu/bader/ • With this I get the CHGCAR and therefore the POSCAR of the structure. • I do a test run on NaCl to make sure I get near to the same results as the bader people

  3. NaCl from bader people:
