We present ab initio pseudopotential–density-functional calculations for the electronic structure of the dilute magnetic semiconductor , with a realistic , in its ordered ferromagnetic phase. We find that it possesses a spin-polarized valence band that could support ideal spin-polarized hole transport. We further find spin-polarized features in the conduction band that could support ideal spin-polarized transport of minority electrons. As such, it emerges as a silicon-lattice-matched candidate material for spintronics applications.

We believe that this level of description is accurate enough for the present problem. This is because for and , use of more advanced methods, such as , or a self-interaction correction, has changed details of the electronic structure, but not the fundamental picture of ideal spin-polarization. See,
