Deskripsi
Spin selectivity for electron transport through peptide monolayers depends on the dipole moment of the system. Here, the authors show that self-assembled monolayers of peptides with α-helix structures transform to more linear structures upon cooling, inducing a flip in the direction of dipole moment and a change in preferred spin for electron transport.
