Latest Patents

Yi-Wun Li holds a patent titled "Detection of polarized spin transport in semiconductors." This patent describes a method and system for estimating the concentration of free electrons with a selected spin polarization in a semiconductor material. The process involves applying a static magnetic field and an electromagnetic field to the semiconductor. Free electrons are injected into the semiconductor material from a ferromagnetic material through diffusion or tunneling. The motion of these injected, spin-polarized electrons generates a Hall voltage across the semiconductor. This voltage is measured at various locations and analyzed to detect the presence of, and estimate the concentration of, free electrons with a selected spin. Additionally, the effects of imposed stress, temperature, illumination, or electromagnetic fields on the semiconductor can be determined.
