Latest Patents

Ching Yao Fong holds a patent for a switching device based on half-metals. This invention provides a mechanism that allows for the variation of a spin-polarized current. The device consists of a first conducting region, a second conducting region, and a half-metal region situated between them. The half-metal region is characterized by having substantially zero available electronic states in a minority spin channel at the intrinsic Fermi level. By altering the voltage of the half-metal region relative to the first conducting region, the Fermi level shifts, which in turn modifies the number of available electronic states in the majority spin channel. This adjustment results in a change in the majority-spin polarized current flowing through the device.
