QQ9.01 - Tuning from Half-Metallic to Semiconducting Behavior in Monolayered SiC and AlN Nanoribbons 
April 25, 2014   8:30am - 8:45am

Half-metallic nanoscale materials are highly sought after for spintronic applications. Using first-principles calculations, we show that the half-metallic and magnetic properties of monolayered hexagonal SiC and AlN zigzagged nanoribbons can exhibit a large tunability under physical and chemical modifications. In a spin-resolved selective self-doping process, AlN ribbons can undergo a transition from half-metallic to fully-metallic or semiconducting behavior with the application of an electric field or uniaxial strain. Also, pristine zigzagged SiC nanoribbons with bare edges are identified as a metal-free material with intrinsic half-metallic behavior which may be tuned with O and S edge functionalization.
