摘要

We report on a theoretical study of spin-dependent electron transport through single-helical molecules connected by two nonmagnetic electrodes, and explain the experiment of significant spin-selective phenomenon observed in α-helical protein and the contradictory results between the protein and single-stranded DNA. Our results reveal that the α-helical protein is an efficient spin filter and the spin polarization is robust against the disorder. These results are in excellent agreement with recent experiments Mishra D, et al. (2013) Proc Natl Acad Sci USA 110(37):14872-14876; G?hler B, et al. (2011) Science 331(6019):894-897 and may facilitate engineering of chiral-based spintronic devices.
