[Pw_forum] ELF .vs. Charge difference

[lan haiping]

Dear All,

   I came to a problem to analyze bond type for an interface.
I wonder about  the difference between electron localization function and
charge difference  with respect to understanding bonding interaction.
In fact , I just read a work of PhysRevLett.89.106403, it seems ELF and
charge difference give the same feature with respect to bonds.
I appreciate any hint  and help.
Thanks
Regards,
