Researchers RIKEN in collaboration with several other Universities, developed an organic solid-state spin filtering device. The device is based on a thin layer of artificial molecular motors.

Undirectional rotation of artificial molecular motors (RIKEN)

The researcher explain that the artificial molecular motors demonstrate four times chirality inversion by light irradiation and thermal treatments during the 360-degree molecular rotation. This means that the spin-polarization direction of electrons that pass through the molecular motors are switched by light irradiation or thermal treatments.
