    The detail is shown here.
    This achievement is a ground breaking discovery and demonstration that an emergent magnetic field can be induced by the application of a strong gate electric field in n-type Si, where the spin-orbit interaction is usually negligible, by focusing on the interfacial Rashba effect, and that the spin can be controlled without using a magnetic field.
