In half metals which have only one type of conduction electron, either spin up or spin down, the current can be completely spin polarized. In this regard, half metals have received attention as promising candidates for spin-based electronic (spintronic) devices. The advantage of using organic materials as spintronic devices is that the spin relaxation length and spin lifetime are considerably long because of weak spin-orbit and hyperfine interactions. In addition, organic materials would be candidates for flexible devices. Here, we introduce graphene-like 2-dimensional organic half metals which are candidates of complete spin polarized carrier sources.
