Prediction for room-temperature half-metallic ferromagnetism in the half-fluorinated single layers of BN and ZnO

On the basis of density functional calculations we explored the possibility that BN and ZnO single layers can become ferromagnetic at room temperature and half-metallic upon fluorine adsorption. Fluorine atoms form stable bonds only with the B and Zn atoms on the graphenelike BN and ZnO single layers, respectively, and the resulting fluorinated BN and ZnO single layers are expected to become ferromagnetic half metals with Curie temperatures around room temperature. The fluorination of semiconductor single layers can lead to interesting spintronics and functional applications. (C) 2010 American Institute of Physics. [doi:10.1063/1.3491416]
