SUMMARY

The discussion centers on Kroger-Vink notation, specifically in the context of donor doping for semiconductors. Participants highlight the importance of balancing matter, charge, and sites in the notation, which is essential for understanding electronic and ionic compensation. The notation's origin is noted as a space-saving method that utilizes periods, apostrophes, or 'x' symbols instead of conventional charge representations like "3-" or "4+". This unique approach is critical for accurately representing complex doping scenarios in semiconductor physics.

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.
