Our model highlight that the lack of inversion symmetry due to the chirality of the potential is a key factor which will lead to a high spin-polarization (SP). We also study the stability of the SP against fluctuations of the electronic structure induced by static disorder affecting the on-site energies. In the energy regions where the spin- filtering occurs, our results remain stable against moderate disorders although the SP is slightly reduced.engbook parthttp://dx.doi.org/10.1063/1.4893525http://aip.scitation.orgopen access538.9Spin-filteringDNA-moleculeshelical fieldAnderson disorderFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
