Hi All..

I'm having some trouble trying to understand the Kroger-Vink notation.. the following example is of donor doping (for semi conductor, extrinsic)..

the first equation is meant to be elecronic compenstaion while the bottom equation is ionic compensation

The key with K-V notation is to simultaneously balance matter, charge, and sites. I believe the notation arose as a way to save space by tilting the typewriter platen and typing one or multiple periods, apostrophes, or xs. Why they couldn't just use the conventional, for example, "3-" or "4+" for charge I don't know.
