New Method Generates Spin Currents in Semiconductors Using Reversible Chirality
Researchers from Science Tokyo have developed a novel method that allows for the dynamic switching of chirality, a property defined by a lack of mirror symmetry. This technique enables the generation of spin currents within semiconductors without the need for magnets. The approach relies on electrochemistry to reversibly insert and remove small chiral molecules from the interlayer gaps of layered, nonchiral semiconductor materials, such as MoS₂.

A new method developed by researchers at Science Tokyo enables the dynamic switching of chirality, which is a specific absence of mirror symmetry. This innovation allows for the generation of spin currents in semiconductor materials.
The technique involves the reversible insertion and removal of small chiral molecules. These molecules are introduced into and extracted from the interlayer gaps of a layered, nonchiral semiconductor material, identified in the original research context as MoS₂.
Electrochemistry plays a crucial role in this process, facilitating the precise control over the insertion and removal of the molecules. This controlled manipulation of chirality directly contributes to the generation of spin currents.
