- Abstract
Results of ab initio band calculations for a layered nonmagnetic SrAgSeF semiconductors consisting of [SrF]/[AgSe] alternating blocks show that the partial O → F substitution leads to a semiconductormetal phase transition due to 'metallization' of the [AgSe] bocks. The oxygen-doped SrAgSeFO phase possesses a metal/semiconductor periodic structure formed by alternating [AgSe] and [SrFO] blocks, respectively. On the contrary, the partial N → F substitution induces a semiconductor-magnetic half-metal phase transition. The resulting SrAgSeFN system may be of interest as a new material for spintronics.
