Magnetic and electronic properties of Mn doped SrISi(111)-(3 × 2) HCC surface

Magnetic semiconductors, can be formed by transition metal on silicon surface, have drown much attention due to the great promise in the application of spintronic devices. Here, we propose two robust antimagnetic semiconductor structures by doping Mn atom on a template that Sr/Si(111)-(3 × 2) honeycomb-chain channel (HCC) surface, using ab initio calculations. Mn atoms are located at insertion site between honeycomb Si chain and Si(111) surface in these two magnetic structures.
