Electrically Driven Spin Currents in DNA
2013
We consider the generation of pure spin currents by electric field driving. First, we discuss the possibility of spin pumping by electric field within a simple two-level bridge model. Then, we apply the scheme to study spin transport in single- and double-stranded DNA junctions. Within a physically relevant range of parameters we show the possibility of generating pure spin currents in DNA, even in the absence of spin–orbit coupling.
