Abstract: A spin-selective conduction structure comprises a crystal having a monolayer of metal atoms between two layers of chiral organic molecules. Each metal atom is coupled to two chiral organic molecules, one at each layer, wherein a chirality of organic molecules in one of the two layers is the same as a chirality of organic molecules in another one of the two layers.
