Electronic and magnetism properties of half-bare zigzag silicon carbon nanoribbons from hybrid density functional calculations

► The half-bare ZSiCNRs with bare Si edge are magnetic metal. ► The half-bare ZSiCNRs with bare C edge are small band gap semiconductor. ► Magnetic coupling of half-bare ZSiCNRs depends on the bare borderline atoms. ► The magnetism of the half-bare ZSiCNRs is stable at room temperature.
