Abstract:
A spin filter includes a first electrode configured to be formed with a zigzag graphene ribbon with an even number of rows extending in a first direction, and to have a magnetic moment in a second direction crossing with the first direction; a second electrode configured to be formed with a zigzag graphene ribbon with an even number of rows extending in the first direction, and to have a magnetic moment in the second direction; and a channel region configured to be placed between the first electrode and the second electrode, and to have an energy level allowing up-spin electrons or down-spin electrons to pass.
