ABSTRACT
Using first principles calculations, we investigate the electronic properties of silicon nanoribbons (SiNRs). We find that the armchair SiNRs can be metals or semiconductors depending on width. For the zigzag SiNRs, the antiferromagnetic semiconducting state is the most stable one. Under transverse electric field, the zigzag SiNRs become half-metals. These results show that SiNRs have both rich electronic and magnetic properties with potential applications in silicon-based electronic and spintronic nanodevices.

    The geometries, electronic structures, and magnetic properties of H-, B-, C-, N-, O-, and F-absorbed MoS2 monolayers have been investigated by first-principles calculations. The results demonstrate that all these atoms can chemically absorb on MoS2 monolayer. The total magnetic moments of H-,...

    We consider the possibility to control multiferroic properties of paraelectric antiferromagnets via biquadratic rotomagnetic (RM) coupling. Using Landau-Ginzburg-Devonshire theory for EuTiO3 as a prototype, we reveal a surprisingly strong influence of the RM coupling in the temperature region of...

    We employ ab-initio electronic structure calculations and study the magnetic properties of CaN and SrN compounds crystallizing in the rocksalt structure. These alkaline-earth metal mononitrides are found to be half-metallic with a total spin magnetic moment per formula unit of 1.0 μB. The...

    Using ab initio calculations, we examine the electronic and magnetic properties of partially open (unzipped) zigzag carbon nanotube (CNT) superlattices. It is found that depending on their opening degree, these superlattices can exhibit multiple localized states around the Fermi energy. More...
