First principles investigations of single dopants in …
In the case of transition-metal dopant in the silicon carbide, it is found that both silicon and carbon substituted nickels in 3C-SiC shows a magnetic-antimagnetic transition under applied strains. The virtual hopping rate of electrons strongly depends on the distance between the spin pair residing in the nickel and dangling bonds.
Doping (semiconductor) - Wikipedia
For the Group IV semiconductors such as diamond, silicon, germanium, silicon carbide, and silicon germanium, the most common dopants are acceptors from Group III or donors from Group V elements. Boron , arsenic , phosphorus , and occasionally gallium are used to dope silicon.
